Alex Richardson a18181931f [NFC][clang] Add a CHECK lines to tests checking offsetof-like expressions
I am looking at constant-folding changes that could affect these tests, so
check that it emits the expected global value instead of just checking

Alex Richardson 3c51b9e270 Fix incorrect GEP bitwidth in areNonOverlapSameBaseLoadAndStore()
When using a datalayout that has pointer index width != pointer size this
code triggers an assertion in Value::stripAndAccumulateConstantOffsets().
I encountered this this while compiling FreeBSD for CHERI-RISC-V.
Also update LoadsTest.cpp to use a DataLayout with index width != pointer
width to ensure this case is tested.

Alex Richardson 547e5e4ae6 [update_llc_test_checks.py] Fix MIPS ASM regex for functions with EH
On MIPS, functions with exception handling code emits an additional
temporary label at the start of the function (due to UseAssignmentForEHBegin):

    _Z8do_catchv:                           # @_Z8do_catchv
    .Ltmp3:
    .set .Lfunc_begin0, .Ltmp3
    .cfi_startproc
    .cfi_personality 128, DW.ref.__gxx_personality_v0
    .cfi_lsda 0, .Lexception0
    .frame	$c11,48,$c17
    .mask 	0x00000000,0
    .fmask	0x00000000,0
    .set	noreorder
    .set	nomacro
    .set	noat
    # %bb.0:                                # %entry

The `[^:]*` regex was terminating the search after .Ltmp<N>: and therefore
not detecting functions with exception handling.

[X86][Costmodel] Load/store i16 Stride=6 VF=16 interleaving costs
The only sched models that for cpu's that support avx2
but not avx512 are: haswell, broadwell, skylake, zen1-3

For this tuple, measuring becomes problematic since there's a lot of spilling going on,
but apparently all these memory ops do not affect worst-case estimate at all here.

For load we have:
https://godbolt.org/z/5qGb9odP6 - for intels `Block RThroughput: <=106.0`; for ryzens, `Block RThroughput: <=34.8`
So pick cost of `106`.

For store we have:

Original message:

    MOVi32imm + ANDWrr ==> ANDWri + ANDWri
    MOVi64imm + ANDXrr ==> ANDXri + ANDXri

    The mov pseudo instruction could be expanded to multiple mov instructions later.
    In this case, try to split the constant operand of mov instruction into two
    bitmask immediates. It makes only two AND instructions intead of multiple
    mov + and instructions.

    Added a peephole optimization pass on MIR level to implement it.

Erich Keane 9324cc2ca9 Change __builtin_sycl_unique_stable_name to just use an Itanium mangling
After significant problems in our downstream with the previous
implementation, the SYCL standard has opted to make using macros/etc to
change kernel-naming-lambdas in any way UB (even passively). As a
result, we are able to just emit the itanium mangling.

However, this DOES require a little work in the CXXABI, as the microsoft
and itanium mangler use different numbering schemes for lambdas.  This
patch adds a pair of mangling contexts that use the normal 'itanium'
mangling strategy to fill in the "DeviceManglingNumber" used previously
by CUDA.

Bjorn Pettersson 460efc1fb8 [Analysis] Be defensive when matching size_t in lib call signatures
When TargetLibraryInfoImpl::isValidProtoForLibFunc is checking
function signatures to detect lib calls it may check that a parameter
or return value matches with the "size_t" type. For this to work it
has to derive the IR type matching with "size_t". Depending on if
a DataLayout is provided or not, this has been done in two different
way. Either a more strict check being based on IntPtrType (which is
given by the DataLayout) or a more relaxed check assuming that any
integer type matches with "size_t".

Given that the stricter approach exist it seems like we do not want
to trigger rewrites etc if we aren't sure that a function calls
actually match with the library function. Therefore it was questioned
why we actually have the more relaxed approach when not being able
to derive an IR type for "size_t". This patch will take a more
defensive approach, requiring that a DataLayout is passed to
isValidProtoForLibFunc.
