ef718b99d4 Provide a fast "get me the target triple from the module" API. This can
drastically reduce the linking time during LTO.

5b3e46bd6b lets go all meta and define new X86 type wrappers that declare the associated
gunk that goes along with an MVT (e.g. reg class, preferred load operation,
memory operand)

e979874e3f introduce a new BinOpRM class and use it to factor AND*rm. This points out
that I need a heavier handed approach to get ultimate factorization.

where !cast is just as short.

0b644ced02 replace stuff like:
let AsmString = !strconcat(
                     !strconcat(!strconcat(opc, "${p}"), !strconcat(".", dt)),
                     !strconcat("\t", asm));

with:

  let AsmString = !strconcat(opc, "${p}", ".", dt, "\t", asm);

reusable, but that is no longer relevant since a split will always replace the
original.

8365ab867e when david added support for #NAME# he didn't update the comments and

38e84dd7ea Another step towards getting rid of static ctors for pass registration: have INITIALIZE_PASS AND INITIALIZE_AG_PASS
expand to an initializeMyPass() function (in additional to the extant static ctors).  Eventually, these will be called
from a big InitializeAllPasses() function, and the PassInfo's they create (which would be leaked if this code were used
at the moment) will be handed off to a PassRegistry for ownership.

8137fd6975 Update SplitEditor API to reflect the fact that the original live interval is
never kept after splitting.

Keeping the original interval made sense when the split region doesn't modify
the register, and the original is spilled. We can get the same effect by
detecting reloaded values when spilling around copies.
