This is useful when replaying tests after the fact and the directories
don't exist anymore.

Summary:
This patch fix the following issues in InstCombiner::visitGetElementPtrInst

    1. Skip for scalable type if transformation requires fixed size number of
    vector element.
    2. Skip for scalable type if transformation relies on compile-time known type
    alloc size.
    3. Use VectorType::getElementCount when scalable property is used to construct
    new VectorType.
    4. Use TypeSize::getKnownMinSize when minimal size of a scalable type is valid to determine GEP 'inbounds'.
    5. Explicitly call TypeSize::getFixedSize to avoid implicit type conversion to uint64_t.

With this patch, .verify.cpp tests explicitly require clang-verify, but
no other test types require clang-verify out of the box. This will allow
making several .fail.cpp tests that don't have any clang-verify markup
to be just .compile.fail.cpp tests, which in turn should allow removing
a long standing workaround that requires parsing tests to detect whether
they have any clang-verify markup in them.

This allows AntiDepBreaker to be used in target specific postRA
scheduler.

On systems with weak memory consistency, this patch fixes an intermittent crash
in the reduction function called by __kmp_hyper_barrier_gather, which suffers
from a race on a child thread's data.

Summary:
The function used to log on Android will cut the message past
a certain amount of characters, which mostly materializes when
dumping the size class map on OOM.

This change splits the log message at newline boundaries.

GCC emits this new form along with others forms(supported in llvm-dwardump)
and since it's support was missing in llvm-dwarfdump, it was not
able to correctly dump the content a debug_macro section for GCC
generated binaries.

This patch extends llvm-dwarfdump to support this form,
now GCC generated debug_macro section can be correctly dumped
using llvm-dwarfdump.

@kamleshbhalui reported that when the Standard Extension M
(Multiplication and Division) is disabled for RISC-V,
`__udivdi3` will call __udivmodti4 which will in turn calls `__udivdi3`.

This patch moves __udivsi3 (shift and subtract) to int_div_impl.inc
`__udivXi3`, optimize a bit, add a `__umodXi3`, and use `__udivXi3` and
`__umodXi3` to define `__udivsi3` `__umodsi3` `__udivdi3` `__umoddi3`.

They don't actually have to, but it makes it easier to unify the
corresponding code and macros. NFC.

Summary:
Only first-faulting and non-faulting loads read/update the FFR register
and hence only the corresponding SDNodes should be decorated with
`SDNPOptInGlue` and `SDNPOutGlue`. This patch:
  * removes SDNPOptInGlue from regular loads stores (FFR is not read)
  * adds SDNPOutGlue to first-faulting and non-faulting loads (FFR is
    both read and updated)

Make it possible to capture reproducers from the API test suite. Given
the symmetry between capture and replay, this patch also adds the
necessary code for replay. For now this is a NO-OP until the
corresponding reproducer instrumentation changes land.

There are no such tests in the libc++ test suite, and I want to move
away from `.fail.cpp` tests (in favour of something else) too, which
require a workaround.

Otherwise all zero values from i1 to i64 collide.

Summary:
This patch adds a mechanism to easily add range checks for a builtin's
immediate operands. This patch is tested with the qdech intrinsic, which takes
both an enum for the predicate pattern, as well as an immediate for the
multiplier.

The directive was a typo when I first wrote the test case, then
decided to use the script and the script didn't remove the line
with the typo.

D77635 added support to recognise primary induction variables for counting-down
loops. This allows us to fold the scalar tail loop into the main vector body,
which we need for MVE tail-predication. This adds some ARM tail-folding test
cases that we want to support.

This test was extracted from D76838, which implemented a different approach to
reverse and thus find a primary induction variable.

Summary:
This issue was introduced when reworking D75861. The bug isn't
actually hit with current unit tests because the contiguous loads/stores
infer the EltType and the MemEltType from the pointer and result, rather
than using the flags. But it will be needed for other intrinsics, such as
gather/scatter.
