[clang] Fix crash when handling nested immediate invocations

Before this patch it was expected that if there was several immediate
invocations they all belong to the same expression evaluation context.
During parsing of non local variable initializer a new evaluation context is
pushed, so code like this
```
namespace scope {
struct channel {
    consteval channel(const char* name) noexcept { }
};
consteval const char* make_channel_name(const char* name) { return name;}

channel rsx_log(make_channel_name("rsx_log"));
}
```
produced a nested immediate invocation whose subexpressions are attached
to different expression evaluation contexts. The constructor call
belongs to TU context and `make_channel_name` call to context of
variable initializer.

This patch removes this assumption and adds tracking of previously
failed immediate invocations, so it is possible when handling an
immediate invocation th check that its subexpressions from possibly another
evaluation context contains errors and not produce duplicate
diagnostics.

[LICM] Don't require optimized uses

LICM currently requests optimized use MSSA form. This is wasteful,
because LICM doesn't actually care about most uses, only those of
invariant pointers in loops. Everything else doesn't need to be
optimized.

LICM already uses the clobber walker in most places. This patch
adjusts one place that was using getDefiningAccess() to use it as
well, so we no longer have a dependence on pre-optimized uses.

This change is not NFC in that the fallback on the defining access
when there are too many clobber calls may now fall back to an
unoptimized use. In practice, I've not seen any problems with this
though. If desired, we could also increase licm-mssa-optimization-cap
to a higher value (increasing this from 100 to 200 has no impact on
average compile-time -- but also doesn't appear to have any impact

Mathieu Fehr [Tue, 4 Apr 2023 19:16:45 +0000 (20:16 +0100)]
[mlir] Introduce IRDL dialect

This patch introduces the IRDL dialect, which allow users to represent
dynamic dialect definitions as an MLIR program.

The IRDL dialect defines operations, attributes, and types, using
attribute constraints. For example:

```
module {
  irdl.dialect @cmath {
    irdl.type @complex {
      %0 = irdl.is f32
      %1 = irdl.is f64
      %2 = irdl.any_of(%0, %1)
      irdl.parameters(%2)
    }

    irdl.operation @norm {
      %0 = irdl.any
      %1 = irdl.parametric @complex<%0>
      irdl.operands(%1)
      irdl.results(%0)
    }
}
```

This program will define a new `cmath.complex` type, which expects a single
parameter, which is either an `f32` or an `f64`. It also defines an
`cmath.norm` operation, which expects a single `cmath.complex` type as operand,
and returns a value of the underlying type. Note that like PDL (which IRDL is
heavily inspired from), both uses of `%0` are expected to be of the same attribute.

IRDL handles attributes and types with the same operations, and does this by always
wrapping types in a `TypeAttr`. This is to simplify the language.

Depends on D144690

[amdgpu] Implement dynamic LDS accesses from non-kernel functions

The premise here is to allow non-kernel functions to locate external LDS variables without using LDS or extra magic SGPRs to do so.

1/ First it crawls the callgraph to work out which external LDS variables are reachable from a given kernel
2/ Then it creates a new `extern char[0]` variable for each kernel, which will alias all the other extern LDS variables because that's the documented behaviour of these variables
3/ The address of that variable is written to a lookup table. The global variable is tagged with metadata to track what address it was allocated at by codegen
4/ The assembler builds the lookup table using the metadata
5/ Any non-kernel functions use the same magic intrinsic used by table lookups of non-dynamic LDS variables to find the address to use

Heavy overlap with the code paths taken for other lowering, in particular the same intrinsic is used to pass the dynamic scope information through the same sgpr as for table lookups of static LDS.

[lld] Support separate native object file path in --thinlto-prefix-replace

Currently, the --thinlto-prefix-replace="oldpath;newpath" option is used during
distributed ThinLTO thin links to specify the mapping of the input bitcode object
files' directory tree (oldpath) to the directory tree (newpath) used for both:

1) the output files of the thin link itself (the .thinlto.bc index files and the
optional .imports files)
2) the specified object file paths written to the response file given in the
--thinlto-index-only=${response} option, which is used by the final native
link and must match the paths of the native object files that will be
produced by ThinLTO backend compiles.
This patch expands the --thinlto-prefix-replace option to allow a separate directory
tree mapping to be specified for the object file paths written to the response file
(number 2 above). This is important to support builds and build systems where the
same output directory may not be written by multiple build actions (e.g. the thin link
and the ThinLTO backend compiles).

The new format is: --thinlto-prefix-replace="origpath;outpath[;objpath]"

This replaces the origpath directory tree of the thin link input files with
outpath when writing the thin link index and imports outputs (number 1
above). If objpath is specified it replaces origpath of the input files with
objpath when writing the response file (number 2 above), otherwise it
falls back to the old behavior of using outpath for this as well.

15 months ago[lld-macho] Check if DWARF offset is too large for compact unwind

[lld-macho] Check if DWARF offset is too large for compact unwind

For functions that use DWARF encodings, their compact unwind entry will
contain a hint about the offset of their DWARF entry from the start of
the `__eh_frame` section. The encoding only has 3 bytes to encode this
hint.

Previously, I neglected to check for overflow (and didn't realize that
the value was merely a hint without needing to be exact.) So for large
`__eh_frame` sections, the hint would overflow and cause the compact
unwind MODE flag to be corrupted, leading to uncaught exceptions at
runtime.

This diff fixes things by encoding zero as the hint for offsets that are
too large. The unwinder will start a linear search at the hint location
for the matching CFI record. The only requirement is that the hint
points to a valid CFI record start, and the start of the section is
always the start of a CFI record (in well-formed programs).

I'm not adding a test for this because generating the test inputs takes
a bit too much time. However, I have been testing locally with this lit
file, which takes about 15s to run on my machine:
