58bfb27c4b Don't allow vextractf128 to be folded with unaligned stores. We don't fold unaligned loads so shouldn't fold unaligned stores as it can cause an alignment fault to occur.

7778ee1ed9 Explicitly mark LEApcrel pseudos with hasSideEffects.
It's not clear that they should be marked as such, but tbb formation
fails if t2LEApcrelJT is hoisted of of a loop.

This doesn't change the flags on these instructions,
UnmodeledSideEffects was already inferred from the missing pattern.

invalid.  However, when parsing an inline asm the mnemonic is at this location.
I don't want to change SMLoc, so use a trivial workaround.

101771ba4d For mips64 switch statements in subroutines could generate
within the codegen EK_GPRel64BlockAddress. This was not 
supported for direct object output and resulted in an assertion.

This change adds support for EK_GPRel64BlockAddress for 
direct object.

One fallout from this is to turn on rela relocations 
for mips64 to match gas.
