Mubuf rtn atomics use GLC_1 thus default value for glc operand
should be -1, see https://reviews.llvm.org/D90730.
This allows us to report error when rtn atomic requires glc=1
but does not have glc operand in input.

Lowers the llvm.masked.gather intrinsics (scalar plus vector addressing mode only)
Changes in this patch:
- Add custom lowering for MGATHER, using getGatherVecOpcode() to choose the appropriate
gather load opcode to use.
- Improve codegen with refineIndexType/refineUniformBase, added in D90942
- Tests added for gather loads with 32 & 64-bit scaled & unscaled offsets.

Previously, loading one from a file meant allowing the library to do the IO.
Clangd would prefer to do such IO itself (e.g. to allow caching).

Since the length of the llvm::SmallVector shufflemask is related to the

the Min field of the ElementCount. This is already done for the similar

We don't act as a language server for these files (e.g. don't get open/close
notifications for them), but just blindly publish diagnostics for them.
This works reasonably well in coc.nvim and vscode: they show up in the
workspace diagnostic list and when you open the file.
The only update after the file is reparsed, not as you type which is a bit
janky, but seems a lot better than nothing.

Currently, Baremetal toolchain requires user to pass a sysroot location
using a --sysroot flag. This is not very convenient for the user. It also
creates problem for toolchain vendors who don't have a fixed location to
put the sysroot bits.
Clang does provide 'DEFAULT_SYSROOT' which can be used by the toolchain
builder to provide the default location. But it does not work if toolchain
is targeting multiple targets e.g. arm-none-eabi/riscv64-unknown-elf which
clang is capable of doing.
This patch tries to solve this problem by providing a default location of
the toolchain if user does not explicitly provides --sysroot. The exact
location and name can be different but it should fulfill these conditions:
1. The sysroot path should have a target triple element so that multi-target
toolchain problem (as I described above) could be addressed.
2. The location should not be $TOP/$Triple as this is used by gcc generally
and will be a problem for installing both gcc and clang based toolchain at
the same location.

On some of the slow or heavily-loaded bots, this test was failing
intermittently because the infinite_loop.py script might not emit
anything to stdout before the 1 second timeout, so the "Command Output"
line isn't present in the output. That output isn't really important to
this test, we just care that the process is killed, so we can just rmove
that check line from the test.

Now that the class does not use a thread, the name is no longer
appropriate. Rename the class to "Server" and make it a long-lived
object (instead of recreating it for every expect_gdbremote_sequence
call). The idea is to make this class a wrapper for all communication
with debug/lldb-server. This will enable some additional cleanups as we
had some duplication between socket_pump non-pump code paths.
Also squeeze in some small improvements:
- use python-level timeouts on sockets instead of the manual select
calls
- use byte arrays instead of strings when working with raw packets
Add tests for this particular detail for x86 and arm (similar tests
already existed for x86_64 and aarch64).
The libssp implementation may be located in a separate DLL, and in
those cases, the references need to be in a .refptr stub, to avoid
needing to touch up code in the text section at runtime (which is
supported but inefficient for x86, and unsupported for arm).

Some Ops in OMP dialect have regions associated with them i.e
`ParallelOp` `MasterOp`. Lowering of these regions involves interfacing
with `OMPIRBuilder` using callbacks, yet there still exist opportunities
for sharing common code in between.
This patch factors out common code into a separate function and adds
support for lowering `MasterOp` using that. Lowering of `ParallelOp` is
also modified appropriately.

While there move some variable declarations to their first

The file was added in 2007 but the functions have never been implemented.
