several fields to make it easier to figure out where bugs might be creeping in.

ppc calls copysignl with a 128 bit ppc long double, resulting
in a node that the type legalizer doesn't know how to expand.

string temporary. This should fix PR6590.

(it seems that FreeBSD doesn't have copysignl).  Done by
removing a bunch of assumptions from the code.  This may also
help with sparc 128 bit floats.

to unify the almost identical code in CodeGenPrepare and InstCombineCalls.

whose true value was not Val#0.

LSDA into the TEXT section. We need to generate non-lazy pointers to it on
Mach-O. However, the object the NLP points to may be local to the translation
unit. If so, then the NLP needs to have the value of that object specified
instead of "0", which the linker interprets as "external".

just make unnamed temp symbols instead of having to come
up with its own names.

where we used ot create an MCSymbol for ".".  Now emit an assembler
temporary label and reference it instead of "." textually.

instead of Pseudo, which helps Thumb decoder to recognize them as Thumb instr.

stpcpy is so similar to strcpy, it doesn't deserve a complete copy of the __strcpy_chk -> strcpy code.

an MCExpr and not an MCSymbol.  Change it to take an MCStreamer,
which is currently unused.

No functionality change.

Bad bad bug. x86 force indirect tail call address into eax when it's meant to force it into a call preserved register instead. Change it to ecx for now.

cl = EXTRACT_SUBREG reg1024, 1, is overly conservative. It should check
for overlaps of vr's live interval with the super registers of the
physical register (ECX in this case) and let JoinIntervals() handle checking
the coalescing feasibility against the physical register (cl in this case).

different codegen.

included when using global symbols to ask the linker for the addresses of
various functions.  One of the symbols was actually getting declared by a
header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
declaration in SearchForAddressOfSpecialSymbol().

MC/Mach-O: Implement "absolutizing" semantics of .set, by evaluating the assembly time value of variables.

 - Also, drop the current location part of AsmLayout, I think I prefer to implement this via explicit symbols.
