Summary:
As this test will create a new target, it will cause all following tests
to fail when running in platform mode, if the new target does not match
the existing architecture (for example, x86 vs x86_64).

Use MachineInstr& to avoid implicit conversions from
MachineBasicBlock::iterator to MachineInstr*. In one case, this could
use a range-based for loop, but the other loops iterated in reverse
order.
One of the reverse-loops checked the MachineInstr* for nullptr, a
condition that is provably unreachable. (And even if my proof has a
flaw, UBSan would catch the bug.)

Summary: The code generation should be independent of the debug info.

Use MachineInstr& instead of MachineInstr* in RegAllocFast to avoid
implicit conversions from MachineInstrBundleIterator. RAFast::spillAll
and RAFast::spillVirtReg still take iterators, since their argument may
be an end iterator from MachineBasicBlock::getFirstTerminator.

Previously out-of-tree passes could detect if LLVM was built with
LLVM_BUILD_32_BITS by looking for -m32 in LLVM_DEFINITIONS, but as of r271871
it no longer appears there. Resolve this by instead emitting LLVM_BUILD_32_BITS
in LLVMConfig so it can be checked for directly.

This feature needs to be explicitly enabled by overriding shouldTraversePostOrder()
as it has performance drawbacks for the iterative Stmt-traversal.

No functional changes. Just created wrapper classes around the 3
and 4 reg mult and mac instruction classes.

This is PR28358
According to
https://www.akkadia.org/drepper/dsohowto.pdf
"The fourth point, the VERS 1.0 version being referred to in the VERS 2.0 definition, is not really important in symbol versioning. It marks the predecessor relationship of the two versions and it is done to maintain the similar- ities with Solaris’ internal versioning. It does not cause any problem it might in fact be useful to a human reader so predecessors should always be mentioned."
Patch partially reverts 273423 "[ELF] - Implemented version script hierarchies.",
version references are just ignored now.

This was reverted in r268740 because of problems with corresponding Clang change.
Clang change was updated and resubmitted in r274220.
Check calling convention in AMDGPUMachineFunction::isKernel
This will be used for AMDGPU_HSA_KERNEL symbol type in output ELF.
Also, in the future unused non-kernels may be optimized.
