[ConstraintSystem] Remove last variable, use move instead of copy. (NFC)
At the moment, a large amount of time is spent construction vectors
by pushing back all elements except the first variable. For large
inputs, such as discussed in https://reviews.llvm.org/D135915#4057050
this can result in excessive compile-time.
Instead, it is more efficient to remove the last variable. Then the
original vector can be re-used by simply popping the last element and
then moving the contents to the new system.
This improves time spent in ConstraintElimination for the linked
reproducer from ~43s to ~3s.

[libc] Remove OpenMP and build the GPU libc directly
The current `libcgpu.a` is actually an archive of fatbinaries. The host
file contains nothing but a section called `LLVM_OFFLOADING` that
contains embedded device code. This used to be handled implicitly by
borrowing the OpenMP toolchain, which did this packaging internally.
Passing the OpenMP flags causes problems with trying to move to testing.
This patch pulls this logic out into the CMake and handles it manually.
This patch is a lot of noise, but it fundamentally comes down to the
following changes.
1. Build the source for every GPU architecture (GPU architectures are
generally not backwards compatible)
2. Combine all of these files into a single binary blob
3. Embed that binary blob into a host file
4. Package these host files into a `.a` archive.
5. The device code will be extracted and managed by the offloading
linker.
Another important point. Right now we are maintaining an important
distinction with the GPU build. That is, when we build the exported
library we will build for many GPU architectures. However, the internal
version will only be built for a single GPU architecture, one that was
found on the user's system. This is intended to be used for internal
testing, very similar to the current path where `libc` is compiled for a
single target triple.

[lldb][SymbolFileDWARF] Support by-name lookup of global variables in inline namespaces
Currently evaluating an expression involving a global variable inside
an inline namespace will fail to lookup said variable. This is because
the `SymbolFileDWARF::FindGlobalVariables` discards from consideration
all DIEs whose decl_context doesn't exactly match that of the lookup.
This patch relaxes this restriction by checking whether C++ rules
would permit the lookup. This is permitted by the DWARFv5 spec in
chapter `3.2.2 Namespace Entries`:
```
A namespace may have a DW_AT_export_symbols attribute which is a flag
which indicates that all member names defined within the namespace may be
referenced as if they were defined within the containing namespace.
```
The motivation for this is evaluating `std::ranges` expressions, which
heavily rely on global variables inside inline namespaces. E.g.,
`std::views::all(...)` is just an invocation of the `operator()`
on `std::ranges::views::__cpo::all`.

knew nothing happened there from the code :-(
These two functions are only called with `Size=8` and `High=true` in two places.
One is in `X86FixupBWInsts.cpp` for liveness of registers and the other is in
`X86AsmPrinter.cpp` for inline asm.
For the first one, we provide an alternative in this patch.
For the second one, the strange behaviour caused a bug that an erorr was not reported for mismatched modifier.
```
void f() {
char x;
asm volatile ("mov %%ah, %h0" :"=r"(x)::"%eax", "%ebx", "%ecx", "%edx", "edi", "esi");
}
```
```
$ gcc -S test.c
error: extended registers have no high halves
```
```
$ clang -S test.c
no error
```
so we fix the bug in this patch.
`getX86SubSuperRegister` is just a wrapper of `getX86SubSuperRegisterOrZero` with a `assert`.
I belive we should remove the latter.

This reverts commit
f514b0e144db063931d19a8ebc2dc42083d0eb2f.
The culprit is that InEC is initialized before Inbound, and Inbound's
initialization happens through a call to openFileForRead. However, the
typical initialization order warnings don't fire; so the behavior was:
Inbound is initialized correctly by openFileForRead; then it's reset to
whatever initializer value (0 originally).
A fix is to move Inbound's decl upfront. I'd still prefer initializing
it to something - and -1 seems like a more appropriate value (it causes
a fail-fast rather than a hang due to trying to read from a
valid-looking but unopen fd).

[flang] Avoid crashing from recursion on very tall expression parse trees
In the parse tree visitation framework (Parser/parse-tree-visitor.h)
and in the semantic analyzer for expressions (Semantics/expression.cpp)
avoid crashing due to stack size limitations by using an iterative
traversal algorithm rather than straightforward recursive tree walking.
The iterative approach is the obvious one of building a work queue and
using it to (in the case of the parse tree visitor) call the visitor
object's Pre() and Post() routines on subexpressions in the same order
as they would have been called during a recursive traversal.
This change helps the compiler survive some artificial stress tests

When scanning dependencies of a module, the command line we're given doesn't have an input file, which the driver needs to be happy. We've been creating a fake in-memory input file named after the module. However, this can hide files/directories on the actual filesystem, leading to errors.
This patch works around that issue by generating a unique file name, which won't collide with the actual file system.
We could also change the driver APIs so that we're able to specify an "assumed" input file. This would be more work, though, since the driver assumes the input name comes from the actual command-line.
