The last one remaining after which emitAnalysis can be removed is when
we convert the LAA's report to a vectorization report. This requires
converting LAA to the new interface first.

The shuffle mask decodes have a large amount of repeated code extracting/splitting mask values from Constant data.
This patch pulls all of this duplicated code into a single helper function to identify undef elements and combine/split constant integer data into the requested shuffle mask elements.
Updated PSHUFB/VPERMIL/VPERMIL2/VPPERM decoders to use it (VPERMV/VPERMV3 could be converted as well in the future).

LLD does not update relocations addends when generate a relocatable
object. That is why we should not write a non-zero GP0 value into
the .reginfo and .MIPS.options sections. And we should not accept input
object files with non-zero GP0 value because we cannot handle them
properly.

In case of linking PIC and non-PIC code together and generation of a
relocatable object, all PIC symbols should have STO_MIPS_PIC flag in the
symbol table of the ouput file.

If we two sections reside in the same PT_LOAD segment,
we compute second section using the following formula:
Off2 = Off1 + VA2 - VA1. This allows OS kernel allocating
sections correctly when loading an image.

Throwing an exception for the first time may lead to call calloc to
allocate memory for __cxa_eh_globals. If the memory pool is exhausted
at that moment, it results in abnormal termination of the program.
This patch addresses the issue by using fallback_malloc in that case.

This adds new pseudo instructions that can be selected during register allocation to represent loads and stores of XMM/YMM registers when AVX512F is available, but VLX isn't. They will be converted to VEX encoded moves if the register turns out to be XMM0-15/YMM0-15. Otherwise either an EVEX VEXTRACT(store) or VBROADCAST(load) will be used.
Fixes one of the cases from PR29112.

a large stack frame with lots of spilled registers.
While writing the i386 version of this test, it looks
like I found a bug in the 32-bit instruction profiler
code. I may ned to fix the assembly inspection engine
before I can finish writing that test, so I'm only
committing the 64-bit one tonight.

Add underscore aliases for strtof_l and strtod_l. _strtold_l exists in
VS 2013 and above, so fix that definition as a drive-by fix.

Inlining the destructor caused the compiler to generate bad IR which failed the Verifier in the backend.

AsmPrinter. This was reinitializing the Mangler after we moved the
Mangler down to TLOF and causing us to have two different unnamed
global values accessed with the same name.
This should fix the problems on the ubsan tests here:
