Original message:

    Fix the values of two xcore ELF flags.

    The values in llvm grew from a pre-MC day when they would not show up
    in .o files and are outside of the SHF_MASKPROC.

    Fortunately the MC output is not currently used as xcore has its own
    assemble and that assembler uses valid values. This updates llvm to
    use the same values as the xmos assembler.

llvm-svn: 293486

Different architectures can have different meaning for flags in the
SHF_MASKPROC mask, so we should always check what the architecture use
before checking the flag.

NFC for now, but will allow fixing the value of an xmos flag.

Summary:
AMDGPU has two register classes with the same set of registers, and this
was causing this tablegen backend would get stuck in infinite recursion.

The patch is correct, but found bugs in other areas that need to be fixed.

[AVX-512] Remove duplicate CodeGenOnly patterns for scalar register broadcast. We can use COPY_TO_REGCLASS like AVX does.

This causes stack spill slots be oversized sometimes, but the same should already be happening with AVX.

This part of the C API is still used in language bindings.

By calling getScalarizationOverhead with the CallInst instead of the types of
its arguments, we make sure that only unique call arguments are added to the
scalarization cost.

getScalarizationOverhead() is extended to handle calls by only passing on the
actual call arguments (which is not all the operands).

This also eliminates a wrapper function with the same name.

Previously this test case fired an assertion in getNode because we tried to create an insert_subvector with both input types the same size and the index pointing to half the vector width.

The primary use of the dump() functions in LLVM is for use in a
debugger. Unfortunately lldb does not seem to handle default arguments
so using `p SomeMI.dump()` fails and you have to type the longer `p
SomeMI.dump(nullptr)`. Remove the paramter to make the most common use
easy. (You can always construct something like `p
SomeMI.print(dbgs(),MyTII)` if you need more features).

Replaces an xor+movd/movq with an xorps which will be shorter in codesize, avoid an int-fpu transfer, allow modern cores to fast path the result during decode and helps other combines recognise an all-zero vector.

The only reason I can think of that we'd want to keep scalar_to_vector in this case is to help recognise the upper elts are undef but this doesn't seem to be a problem.

While this probably should be considered a dump debugger utility, the C
API currently has no other ways to print a module to stderr for error
reporting purposes, so keep it even in release builds.

PACKUSWB converts Signed word to Unsigned byte, (the same about DW) and it can't be used for umin+truncate pattern.
AVX-512 VPMOVUS* instructions fit the pattern since they convert Unsigned to Unsigned.
