Quentin Colombet 6feaf82088 [RegBankSelect] Explain what it would take to support non-copy
repairing.

Copies are easy because we repair only when there is a mismatch. For
non-copy repairing, i.e., cases that involves breaking down or gathering
up the value, one of the operand may not have a register bank yet. Thus,
derivate a cost from that, requires more work.

Oliver Stannard b3378e2f3c [ARM] MSR instructions implicitly set CPSR
The MSR instructions can write to the CPSR, but we did not model this
fact, so we could emit them in the middle of IT blocks, changing the
condition flags for later instructions in the block.

The tests use two calls to llvm.write_register.i32 because it is valid
to use these instructions at the end of an IT block, which if conversion
does do in some cases. With two calls, the first clobbers the flags, so
a branch has to be used to make the second one conditional.

Haojian Wu 13d3048ced [include-fixer] Keep dot dot in SymbolInfo file paths.
Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").

Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

Chris Dewhurst 7e7ee962f6 [Sparc] Complex return value ABI compliance.
According to the Sparc V8 ABI, complex numbers should be passed and returned as pairs of registers:

https://docs.oracle.com/cd/E26502_01/html/E28387/gentextid-2734.html

This fix ensures this is the case. Without this, complex numbers are returned as a struct of two floats, which breaks the ABI rules.

Saleem Abdulrasool 1ef925f0bd Support: correct AArch64 TargetParser implementation
The architecture enumeration is shared across ARM and AArch64.  However, the
data is not.  The code incorrectly would index into the array using the
architecture index which was offset by the ARMv7 architecture enumeration.  We
do not have a marker for indicating the architectural family to which the
enumeration belongs so we cannot be clever about offsetting the index (at least
it is not immediately apparent to me).  Instead, fall back to the tried-and-true
method of slowly iterating the array (its not a large array, so the impact of
this is not too high).

Because of the incorrect indexing, if we were lucky, we would crash, but usually
we would return an invalid StringRef.  We did not have any tests for the AArch64
target parser previously;.  Extend the previous tests I had added for ARM to
cover AArch64 for ensuring that we return expected StringRefs.

Take the opportunity to change some iterator types to references.

This work is needed to support parsing `.arch name` directives in the AArch64
target asm parser.

Martin Probst 6f43efbdde clang-format: [JS] fix an assertion failure caused by shrinking sources.
Summary:
The JavaScript import sorter has a corner condition that can cause the overall
source text length to shrink. This change circumvents the issue by appending
trailing space in the line after the import blocks to match at least the
previous source code length.

This needs a better long term fix, but this fixes the immediate issue.
