Converted an overly aggressive assert to a conditional check in AddCombineTo64bitMLAL.
Said assert assumes that ADDC will always have a glue node as its second
argument and is checked before we even know that we are actually performing the
relevant MLAL optimization. This is incorrect since on ARM we *CAN* codegen ADDC
with a use list based second argument. Thus to have both effects, I converted
the assert to a conditional check which if it fails we do not perform the
optimization.
In terms of tests I can not produce an ADDC from the IR level until I get in my
multiprecision optimization patch which is forthcoming. The tests for said patch
would cause this assert to fail implying that said tests will provide the
relevant tests.

Mips ELF: Mark object file as ABI compliant
When producing objects that are abi compliant we are
marking neither the object file nor the assembly file
correctly and thus generate warnings.
We need to set the EF_CPIC flag in the ELF header when
generating direct object.
Note that the warning is only generated when compiling without PIC.
When compiling with clang the warning will be suppressed by supplying:
-Wa,-mno-shared -Wa,-call_nonpic
Also the following directive should also be added:
.option pic0
when compiling without PIC, This eliminates the need for supplying:
-mno-shared -call_nonpic

A bug in libObject will cause it to assert() if a symbol table's string
table and the section header string table are the same section, so we
need to ensure that we emit two different string tables (among other
things). The problematic code is the hardcoded usage of ".strtab"
(`dot_strtab_sec`) for looking up symbol names in
ELFObjectFile<ELFT>::getSymbolName.
I discussed this with Michael, and he has some local improvements to the
ELF code in libObject that, among other things, should fix our handling

Switch spill weights from a basic loop depth estimation to BlockFrequencyInfo.
The main advantages here are way better heuristics, taking into account not
just loop depth but also __builtin_expect and other static heuristics and will
eventually learn how to use profile info. Most of the work in this patch is
pushing the MachineBlockFrequencyInfo analysis into the right places.
This is good for a 5% speedup on zlib's deflate (x86_64), there were some very
unfortunate spilling decisions in its hottest loop in longest_match(). Other
benchmarks I tried were mostly neutral.
This changes register allocation in subtle ways, update the tests for it.
