[llvm][mlir][OpenMP] Support translation for linear clause in omp.wsloop and omp.simd (#139386)
This patch adds support for LLVM translation of linear clause on
omp.wsloop (except for linear modifiers).
[RISCV][llvm] Support VFADD, VFSUB, VFMUL codegen for Zvfbfa (#170612)
Support both fixed-length vectors and scalable vectors.
Note: VP version is not gonna be supported for trivial instructions
since they're going to be removed soon.
[RISCV][llvm] Support PSLL codegen for P extension (#170074)
There's no instruciton for vector shift amount, so we have to scalarize
it and rebuild the vector.
[RISCV] Inserting indirect jumps with X7 for Zicfilp (#170683)
`BranchRelxation` uses `RISCVInstrInfo::insertIndirectBranch` to insert
an indirect branch if the jump target is out of range. Currently it uses
register scavenging to find a free register to use for the indirect
target. If Zicfilp is enabled, we need to use X7 so that the jump will
be treated as a software guarded branch.

[MLIR] Add fusability query to TilingInterface (#166502)
This introduces `isOpFusableWithProducer/Consumer` methods to the
TilingInterface that enable querying whether a tilable op can be fused
into a given set of producer slices or consumer slice without generating
IR. This is needed to enable use of the tiling interface in pattern
rewrites, as without this any pattern rewrite that tries to invoke the
method to tile is allowed to generate IR and fail.
[libclc] Add OpenCL atomic_*_explicit builtins (#168318)
Implement atomic_*_explicit (e.g. atomic_store_explicit) with
memory_order plus optional memory_scope.
OpenCL memory_order maps 1:1 to Clang (e.g. OpenCL memory_order_relaxed
== Clang __ATOMIC_RELAXED), so we pass it unchanged to clc_atomic_*
function which forwards to Clang _scoped_atomic* builtins.
Other changes:
* Add __opencl_get_clang_memory_scope helper in opencl/utils.h (OpenCL
scope -> Clang scope).
* Correct atomic_compare_exchange return type to bool.
* Fix atomic_compare_exchange to return true when value stored in the
pointer equals expected value.
* Remove volatile from CLC functions so that volatile isn't present in
LLVM IR.
* Add '-fdeclare-opencl-builtins -finclude-default-header' flag to
include

Add a `breakpoint add` command to fix the option-madness that is `breakpoint set` (#156067)
Someone came up with a clever idea for a new breakpoint type, but we
couldn't figure out how to add it in an ergonomic way because
`breakpoint set` has used up all the short-option characters. And even
if they did find a way to add it, the help for `break set` is so
confusing - because of the way it is implemented - that very few people
would detect the addition.
The basic problem is that `break set` distinguishes amongst the
fundamental breakpoint types it offers by which "required option" you
provide. If you pass a `-a` you are setting an address breakpoint, if
`-n`, `-F`, etc. a symbol name based breakpoint. And so forth. That is
however pretty hard to discern from the option grouping printing from
`help break set`. `break set` also suffers from the problem that it uses
common options in different ways depending on which "required" option is
present, which makes documenting the various behaviors difficult. And as
we run out of single letters it makes extending it difficult to
impossible.

build_llvm_release.bat: Use absolute path when building the tarball (#169951)
The rest of the script uses an absolute path for the llvm source
directory too.
[Clang][OpenCL] Add support for the cl_intel_subgroup_buffer_prefetch (#170532)
The commit adds support for the cl_intel_subgroup_buffer_prefetch OpenCL
extension. The extension introduces a new built-in functions that allow
prefetching data from a global memory to caches as a subgroup-level
operation.
The extension is defined here:

[clang-doc] Remove uses of consumeError (#168759)
In BitcodeReader, we were using consumeError(), which drops the error
and hides it from normal usage. To avoid that, we can just slightly
tweak the API to return an Expected<T>, and propagate the error
accordingly.
