913fc0e3df Re-commit r221056 and others with fix, "[mips] Move F128 argument handling into MipsCCState as we did for returns. NFC."
sret arguments can never originate from an f128 argument so we detect
sret arguments and push false into OriginalArgWasF128.

  r221061 "Renamed CCState members that appear to misspell 'Processed' as 'Proceed'. NFC."

It cuased an undefined behavior in LLVM :: CodeGen/Mips/return-vector.ll.

b80f5bf3cf [mips] Move all ByVal handling into CCState and tablegen-erated code. NFC.
Summary:
CCState already contains a byval implementation that is very similar to the
Mips custom code. This patch merges the custom code into the existing
common code and tablegen-erated code.

f65f1c04c4 [mips] For indirect calls we don't need $gp to point to .got. Mips linker
doesn't generate lazy binding stub for a function whose address is taken in
the program.

da144ed5a2 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

76c7b7a591 Add alignment value to allowsUnalignedMemoryAccess
Rename to allowsMisalignedMemoryAccess.

On R600, 8 and 16 byte accesses are mostly OK with 4-byte alignment,
and don't need to be split into multiple accesses. Vector loads with
an alignment of the element type are not uncommon in OpenCL code.

7b69102edb Add address space argument to allowsUnalignedMemoryAccess.
On R600, some address spaces have more strict alignment
requirements than others.

8176eeb183 Fix a regression I introduced when I expanded the complex pseudos in
the Mips16 port. A few of the psuedos could either take signed
or unsigned arguments and I did not distinguish the case and improperly
rejected some valid cases that the assembler had previously accepted
when they were pure pseudos that expanded as assembly instructions.
