This commit added stride support in runtime array types. It also
adjusted the assembly form for the stride from `[N]` to `stride=N`.
This makes the IR more readable, especially for the cases where
one mix array types and struct types.

Summary:
Share logic to strip debugify metadata between the IR and MIR level
debugify passes. This makes it simpler to hunt for bugs by diffing IR
with vs. without -debugify-each turned on.
As a drive-by, fix an issue causing CallGraphNodes to become invalid
when a dead llvm.dbg.value prototype is deleted.

Rename extract-instrmap-aarch64.test to extract-instrmap.test because
the path component `AArch64` conveys the target name clearly.
Additionally, adopt a convention we start to use in LLVM binary
utilities: prepend `#` to CHECK/RUN lines and `##` to comment lines even
if the file contains no code. The notation makes CHECK/RUN/comments
stand out.

We can use it when just the value doesn't require destruction. Empty
keys are safe to overwrite always. This gets the important case of
std::pair values.
Summary: Current implementation mixed everything up so that there is almost no encapsulation. In this patch, all CUDA related operations are put into a new class DeviceRTLTy and only necessary functions are exposed. In addition, all C++ code now conforms with LLVM code standard, keeping those API functions following C style.

Since 1725f28841, this should check
isFMADLegalForFAddFSub rather than the the plain isOperationLegal.
This would assert in a subset of cases due to an oddity in how FMAD is
selected. We will allow FMA formation pre-legalize, but not FMAD even
in cases where it would be valid.
The current hook requires passing in the root fadd/fsub. However, in
this distributed case, this would be far more complicated to pass in
the relevant operand. AMDGPU doesn't get any value from the node, and
only needs the type and is the only implementor, so I'm not sure why
we have this complexity. Just rename and expand the assert to avoid
the more complicated checks spread through the distribution logic.
The shuffle decoding is used by X86ISelLowering and
MCTargetDesc/X86InstComments. The latter used to be in a
separate InstPrinter library. The Utils library existed to allow
InstPrinter and CodeGen to share the shuffle decoding. Since
X86InstComments now lives in the MCTargetDesc, which CodeGen
already depends on, we can sink the shuffle decoding there as well.

We already print available features, and it can be useful to print
substitutions as well since those are a pretty fundamental part of
a test suite. We could also consider printing other things like the
test environment, however the need doesn't appear to be as strong.
As a fly-by fix, we also always print available features, even when
there are none.

Summary:
Fold (shift (shift X, C2), C1) -> (shift X, (C1 + C2)) for logical as
well as arithmetic shifts. This is needed to prevent regressions from
an upcoming funnel shift expansion change.
While we're here, fold (VSRAI -1, C) -> -1 too.

Differential Revision: https://reviews.llvm.org/D77974
Summary:
clang-format currently puts the first enumerator on the same line as the
enum keyword and opening brace if it fits (for example, for anonymous
enums if IndentWidth is 8):
$ echo "enum { RED, GREEN, BLUE };" | clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum { RED,
GREEN,
BLUE };
This doesn't seem to be intentional, as I can't find any style guide that
suggests wrapping enums this way. Always force the enumerator to be on a new
line, which gets us the desired result:
$ echo "enum { RED, GREEN, BLUE };" | ./bin/clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum {
RED,
GREEN,
BLUE
};
Test Plan:
New test added. Confirmed test failed without change and passed with change by
running:

Improve the chances of folding the writemask into the combined shuffle by scaling a wider shuffle mask to match the root's original type.
This creates a few minor issues with variable shuffles, preventing combines of shuffles because of the more limited support binary shuffle types. In most cases we're probably better off combining the shuffles and losing the writemask fold, but this isn't always going to be true.
Now that's D77928 landed we need to try harder to match shuffle and mask widths. This is a couple of tests showing where variable shuffle masks have been widened preventing them from folding with the mask.

Widening a selects depends on whether the condition is loop invariant or
not. Rather than checking during codegen-time, the information can be
recorded at the VPlan construction time.
This was suggested as part of D76992, to reduce the reliance on
accessing the original underlying IR values.
