By moving them into a folder with a local lit config
requiring x86. All these tests use x86 target triples.
There are two tests that require target-x86_64 because
they run program files (instead of just needing the backend).
Those are moved to the x86 folder also but their REQUIRES are
unchanged.

This is a work-in-progress implementation of an assembler for M68k.
Outstanding work:
- Updating existing tests assembly syntax
- Writing new tests for the assembler (and disassembler)
I've left those until there's consensus that this approach is okay (I hope that's okay!).
Questions I'm aware of:
- Should this use Motorola or gas syntax? (At the moment it uses Motorola syntax.)
- The disassembler produces a table at runtime for disassembly generated from the code beads. Is this okay? (This is less than ideal but as I mentioned in my llvm-dev post, it's quite complicated to write a table-gen parser for code beads.)

In all this time, we've never used more than one delegate. The logic to
support multiple delegates is therefore untested, and becomes
particularly unwieldy once we need to support multiple processes.
Just remove it.
This patch introduces the neccessary infrastructure changes to implement
cost-modelling for detensoring. In particular, it introduces the
following changes:
- An extension to the dialect conversion framework to selectively
convert sub-set of non-entry BB arguments.
- An extension to branch conversion pattern to selectively convert
sub-set of a branche's operands.
- An interface for detensoring cost-modelling.
- 2 simple implementations of 2 different cost models.
This sets the stage to explose cost-modelling for detessoring in an
easier way. We still need to come up with better cost models.

We should consider the feeder user number when we do reverse memory

Previous automatic-ref-counting pass worked with high level async operations (e.g. async.execute), however async values reference counting is a runtime implementation detail.
New pass mostly relies on the save liveness analysis to place drop_ref operations, and does better verification of CFG with different liveIn sets in block successors.
This is almost NFC change. No new reference counting ideas, just a cleanup of the previous version.

This is similar to the definition of llvm.switch, providing
unstructured branch-based control flow. It differs from the LLVM
operation in that it accepts any signless integer (not only an i32),
takes no branch weights (the same as the Branch and CondBranch ops),
and has a slightly different syntax for the default case that includes
it in the list of cases with an explicit `default` keyword.
Also included are several canonicalizers.

Since c42c67ad ('Re-apply "[lli] Make -jit-kind=orc the default JIT

ignore the --entry-function flag, which breaks all tests that
use the flag, namely the AMX and X86Vector integration tests.

This reverts commit 3842de49f6.
It fails to build, with errors such as:
GDBRemoteCommunicationClient.cpp:1005:20:
error: no viable overloaded '='
avail_name = compression;
Jump threading can replace select then unconditional branch with
conditional branch, but when doing so loses debug info.
This destructive transform is eventually leading to a failed Verifier
run during full LTO builds of the Linux kernel with CFI and KCOV
enabled, as reported in PR39531.
ModuleSanitizerCoveragePass will insert calls to
__sanitizer_cov_trace_pc, and sometimes split critical edges,
using whatever debug info may or may not exist for the branch for
the added libcall. Since we can inline calls to
__sanitizer_cov_trace_pc due to LTO, this can lead to the error
observed in PR39531 when the debug info isn't propagated to
the libcall, because of prior destructive transforms that failed to
retain debug info.

Turning on -fstrict-vtable-pointers in Chrome caused an extra global
initializer. Turns out that a llvm.strip.invariant.group intrinsic was
causing GlobalOpt to fail to step through some simple code.
We can treat *.invariant.group uses as simply their operand.
Value::stripPointerCastsForAliasAnalysis() does exactly this. This
should be safe because the Evaluator does not skip memory accesses due
to invariants or alias analysis.
However, we don't want to leak that we've stripped arbitrary pointer
casts to users of Evaluator, so we bail out if we evaluate a function to
any constant, since we may have looked through *.invariant.group calls
and aliasing pointers cannot be arbitrarily substituted.

Instruction::getDebugLoc can return an invalid DebugLoc. For such cases
where metadata was accidentally removed from the libcall insertion
point, simply insert a DILocation with line 0 scoped to the caller. When
we can inline the libcall, such as during LTO, then we won't fail a
Verifier check that all calls to functions with debug metadata
themselves must have debug metadata.

These patterns have been used as a prerequisite step for lowering
to SPIR-V. But they don't involve SPIR-V dialect ops; they are
pure memref/vector op transformations. Given now we have a dedicated
MemRef dialect, moving them to Memref/Transforms/, which is a more
suitable place to host them, to allow used by others.
This commit just moves code around and renames patterns/passes
accordingly. CMakeLists.txt for existing MemRef libraries are

This support code is used by clang-rename and other tools that might not

Currently field designated initializer are not supported.
So, renaming S::a to S::b in this code:
S s = { .a = 10 };
will not extract the field designated initializer for a (the 'a' after the
dot).
This patch adds support for field designated initialized to
RecursiveSymbolVisitor and RenameLocFinder that is used in

Summary:
When building with gcc on AIX, it seems that gcc does not like the
`always_inline` without the `inline` keyword.
So adding the inline keywords in for __open in ifstream and ofstream.
That will also make it consistent with __open in basic_filebuf
(it seems we added `inline` there before for gcc build as well).
