Summary:
N32 support will follow in a later patch since the symbol version of 'la'
incorrectly believes N32 to have 64-bit pointers and rejects it early.
This fixes the three incorrectly expanded 'la' macros found in bionic.

Summary:
The MIPS IAS can now pass 'ninja check-all', recurse, build a bootable linux
kernel, and pass a variety of LNT testing.
Unfortunately we can't enable it by default for 64-bit targets yet since the N32
ABI is still very buggy and this also means we can't enable it for N64 either
because we can't distinguish between N32 and N64 in the relevant code.

Summary:
Previously, we were inserting an InlineAsm statement for each line of the
inline assembly. This works for GAS but it triggers prologue/epilogue
emission when IAS is in use. This caused:
.set noreorder
.cpload $25
to be emitted as:
.set push
.set reorder
.set noreorder
.set pop
.set push
.set reorder
.cpload $25
.set pop
which led to assembler errors and caused the test to fail.
The whitespace-after-comma changes included in this patch are necessary to
match the output when IAS is in use.

Summary:
The -mcpu=mips16 option caused the Integrated Assembler to crash because
it couldn't figure out the architecture revision number to write to the
.MIPS.abiflags section. This CPU definition has been removed because, like
microMIPS, MIPS16 is an ASE to a base architecture.

Essentially the same as the GEP change in r230786.
A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)
import fileinput
import sys
import re
pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")
for line in sys.stdin:
sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Hard float for mips16 means essentially to compile as soft float but to
use a runtime library for soft float that is written with native mips32
floating point instructions (those runtime routines run in mips32 hard
float mode).
The patch reviewed by Reed Kotler.
