The handling of 'funsafe-math-optimizations' doesn't update the 'MathErrno'
flag. But the driver checks for 'fno-math-errno' before passing
'funsafe-math-optimizations' to the FE. In GCC, the option
'funsafe-math-optimizations' doesn't affect the 'fmath-errno' flag.
This patch aligns clang with GCC.
'-ffast-math' sets the FPContract to 'fast'. But 'funsafe-math-optimizations'
the driver doesn't consider the FPContract when handling the option.
Unfortunately there are places in the BE that interpret unsafe math
mode as allowing FMA. This patch makes -ffast-math' and
'funsafe-math-optimizations' behave similarly in regard to the setting of the
FPContract.

[mlir][bufferize] Eliminate tensor.empty ops instead of bufferization.alloc_tensor ops
tensor.empty op elimination is an optimization that brings IR in a more bufferization-friendly form. E.g.:
```
%0 = tensor.empty()
%1 = linalg.fill(%cst, %0) {inplace = [true]}
%2 = tensor.insert_slice %1 into %t[10][20][1]
```
Is rewritten to:
```
%0 = tensor.extract_slice %t[10][20][1]
%1 = linalg.fill(%cst, %0) {inplace = [true]}
%2 = tensor.insert_slice %1 into %t[10][20][1]
```
This optimization used to operate on bufferization.alloc_tensor ops. This is not correct because the documentation of bufferization.alloc_tensor says that it always bufferizes to an allocation. Instead, this optimization should operate on tensor.empty ops, which can then be lowered to bufferization.alloc_tensor ops (if they don't get eliminated).

[mlir] Introduce device mapper attribute for `thread_dim_map` and `mapped to dims`
`scf.foreach_thread` defines mapping its loops to processors via an integer array, see an example below. A lowering can use this mapping. However, expressing mapping as an integer array is very confusing, especially when there are multiple levels of parallelism. In addition, the op does not verify the integer array. This change introduces device mapping attribute to make mapping descriptive and verifiable. Then it makes GPU transform dialect use it.
```
scf.foreach_thread (%i, %j) in (%c1, %c2) {
scf.foreach_thread (%i2, %j2) in (%c1, %c2)
{...} { thread_dim_mapping = [0, 1]}
} { thread_dim_mapping = [0, 1]}
```
It first introduces a `DeviceMappingInterface` which is an attribute interface. `scf.foreach_thread` defines its mapping via this interface. A lowering must define its attributes and implement this interface as well. This way gives us a clear validation.
The change also introduces two new attributes (`#gpu.thread<x/y/z>` and `#gpu.block<x,y,z>` ). After this change, the above code prints as below, as seen here, this way clarifies the loop mappings. The change also implements consuming of these two new attribute by the transform dialect. Transform dialect binds the outermost loops to the thread blocks and innermost loops to threads.
```
scf.foreach_thread (%i, %j) in (%c1, %c2) {
scf.foreach_thread (%i2, %j2) in (%c1, %c2)

[LTO] Make local linkage GlobalValue in non-prevailing COMDAT available_externally
For a local linkage GlobalObject in a non-prevailing COMDAT, it remains defined while its
leader has been made available_externally. This violates the COMDAT rule that
its members must be retained or discarded as a unit.
To fix this, update the regular LTO change D34803 to track local linkage
GlobalValues, and port the code to ThinLTO (GlobalAliases are not handled.)
This fixes two problems.
(a) `__cxx_global_var_init` in a non-prevailing COMDAT group used to
linger around (unreferenced, hence benign), and is now correctly discarded.
```
int foo();
inline int v = foo();
```
(b) Fix https://github.com/llvm/llvm-project/issues/58215:
as a size optimization, we place private `__profd_` in a COMDAT with a
`__profc_` key. When FuncImport.cpp makes `__profc_` available_externally due to
a non-prevailing COMDAT, `__profd_` incorrectly remains private. This change
makes the `__profd_` available_externally.
```
cat > c.h <<'eof'
extern void bar();
inline __attribute__((noinline)) void foo() {}
eof
cat > m1.cc <<'eof'
#include "c.h"
int main() {
bar();
foo();
}
eof
cat > m2.cc <<'eof'
#include "c.h"
__attribute__((noinline)) void bar() {
foo();
}
eof

rm -fr t && ./t_gen && llvm-profdata show -function=foo t/default_*.profraw
clang -O2 -fprofile-generate=./t m1.cc m2.cc -flto=thin -fuse-ld=lld -o t_gen
rm -fr t && ./t_gen && llvm-profdata show -function=foo t/default_*.profraw
```
If a GlobalAlias references a GlobalValue which is just changed to
available_externally, change the GlobalAlias as well (e.g. C5/D5 comdats due to
cc1 -mconstructor-aliases). The GlobalAlias may be referenced by other
available_externally functions, so it cannot easily be removed.
Depends on D137441: we use available_externally to mark a GlobalAlias in a
non-prevailing COMDAT, similar to how we handle GlobalVariable/Function.
GlobalAlias may refer to a ConstantExpr, not changing GlobalAlias to
GlobalVariable gives flexibility for future extensions (the use case is niche.
For simplicity we don't handle it yet). In addition, available_externally
GlobalAlias is the most straightforward implementation and retains the aliasee
information to help optimizers.
See windows-vftable.ll: Windows vftable uses an alias pointing to a
private constant where the alias is the COMDAT leader. The COMDAT use case
is skeptical and ThinLTO does not discard the alias in the non-prevailing COMDAT.
This patch retains the behavior.

[lldb][test] TestConstStaticIntegralMember.py: fix for clang-{9,11,13}
**Summary**
The public lldb matrix bot is failing for tests compiled with clang-9, clang-11, clang-13.
This patch addresses these failures by evaluating the enum case that
doesn't cause malformed DWARF in older version of clang.
There was no particular reason we had to use `true` enum case
to reproduce the bug in #58383, so simply switch to use `false`
to get all bots passing again.
**Details**
In older versions of clang, the following snippet:
```
enum EnumBool : bool {
enum_bool_case1 = false,
enum_bool_case2 = true,
};
struct A {
const static EnumBool enum_bool_val = enum_bool_case2;
};
```
…results in following DWARF:
```
0x00000052: DW_TAG_structure_type
DW_AT_calling_convention (DW_CC_pass_by_value)
DW_AT_name ("A")
DW_AT_byte_size (0x01)
DW_AT_decl_file ("/Users/michaelbuch/Git/llvm-project/lldb/test/API/lang/cpp/const_static_integral_member/repro.cpp")
DW_AT_decl_line (6)
0x0000005b: DW_TAG_member
DW_AT_name ("enum_bool_val")
DW_AT_type (0x0000000000000068 "const EnumBool")
DW_AT_decl_file ("/Users/michaelbuch/Git/llvm-project/lldb/test/API/lang/cpp/const_static_integral_member/repro.cpp")
DW_AT_decl_line (7)
DW_AT_external (true)
DW_AT_declaration (true)
DW_AT_const_value (-1)
```
Note the `DW_AT_const_value == -1`
When evaluating `A::enum_bool_val` in the lldb we get:
```
(lldb) p A::enum_bool_val
error: expression failed to parse:
error: Couldn't lookup symbols:
__ZN1A13enum_bool_valE
```
Enabling the DWARF logs we see:
```
(arm64) clang-13.out: DWARFASTParserClang::ParseTypeFromDWARF (die = 0x00000068, decl_ctx = 0x136ac1e30 (die 0x0000000b)) DW_TAG_const_type name = '(null)')
Failed to add const value to variable A::enum_bool_val: Can't store unsigned value
18446744073709551615 in integer with 1 bits.
```
This occurs because a boolean enum is considered an unsigned integer
type, but we try to initialize it with a `-1`.
**Testing**
- Confirmed locally that top-of-tree lldb correctly
evaluates the previously failing expression when
the test program is compiled with clang-13

This patch adds the -fpass-plugin option to flang which dynamically loads LLVM
passes from the shared object passed as the argument to the flag. The behavior
of the option is designed to replicate that of the same option in clang and
thus has the same capabilities and limitations.
Features:
Multiple instances of -fpass-plugin=path-to-file can be specified and each
of the files will be loaded in that order.
The flag can be passed to both flang-new and flang-new -fc1.
The flag will be listed when the -help flag is passed to both flang-new and
flang-new -fc1. It will also be listed when the --help-hidden flag is passed.
Limitations:
Dynamically loaded plugins are not supported in clang on Windows and are not
supported in flang either.

Some minor stylistic changes are made in the files that were modified to
enable this functionality. Those changes make the naming of functions more
consistent, but do not change any functionality that is not directly
