Chris Lattner 1fc81e90f7 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)

Chris Lattner eadaeaab93 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.

Chris Lattner 9402633637 remove the !nameconcat tblgen feature. It "shorthand" and only used in 4 places 
where !cast is just as short.

Sean Callanan 2ab40fecf6 Updated the expression parser to ignore non-external 
functions it finds in libraries unless it cannot find
an external function with the desired name.

Chris Lattner 04c342ea20 replace stuff like: 
let AsmString = !strconcat(
                     !strconcat(!strconcat(opc, "${p}"), !strconcat(".", dt)),
                     !strconcat("\t", asm));

with:

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

:)

!strconcat(!strconcat(!strconcat(!strconcat

Simplify some x86 td files to use it.

Owen Anderson c25b39702f 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.

John McCall 09d1369964 When instantiating a new-expression, force a rebuild if there were default 
arguments in either the placement or constructor arguments.  This is
important if the default arguments refer to a declaration or create a
temporary.

Jakob Stoklund Olesen 89d276aa48 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.
