5c58a3168f Make VAARG work with x86 long double (which is 
10 bytes long, but is passed in 12/16 bytes).

8f4d5eb9e5 Don't crash analyzing certain quadratics (addrec of {X,+,Y,+,1}). 
We're still waiting on code that actually analyzes them properly.

6feb333695 Changes from Duncan's review: 
* merge two weak functions by making them both alias a third non-weak fn
 * don't reimplement CallSite::hasArgument
 * whitelist the safe linkage types

579a024661 Add a new MergeFunctions pass. It finds identical functions and merges them. 
This triggers only 60 times in llvm-test (look at .llvm.bc, not .linked.rbc)
and so it probably wont be turned on by default. Also, may of those are likely
to go away when PR2973 is fixed.

c5e1ec47c7 Add InlineCost class for represent the estimated cost of inlining a 
function.
 - This explicitly models the costs for functions which should
   "always" or "never" be inlined. This fixes bugs where such costs
   were not previously respected.

d976c21241 Resolve bug 2947: vararg-marked functions must spill registers R3-R79 to stack 
so that va_start/va_arg/et.al. will walk arguments correctly for Cell SPU.

N.B.: Because neither clang nor llvm-gcc-4.2 can be built for CellSPU, this is
still unexorcised code.

57760d96e2 Fix darwin ppc llvm-gcc build breakage: intercept 
ppcf128 to i32 conversion and expand it into a code
sequence like in LegalizeDAG.  This needs custom
ppc lowering of FP_ROUND_INREG, so turn that on and
make it work with LegalizeTypes.  Probably PPC should
simply custom lower the original conversion.

4002a1b6f1 Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized 
a memset using 16-byte XMM stores, but where the stack realignment code
didn't work.  Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.

This is part of PR2888

4047f4a0b4 Fix translateX86CC: if SetCCOpcode is SETULE and 
LHS is a foldable load, then LHS and RHS are swapped
and SetCCOpcode is changed to SETUGT.  But the later
code is expecting operands to be the wrong way round
for SETUGT, but they are not in this case, resulting
in an inverted compare.  The solution is to move the
load normalization before the correction for SETUGT.
This bug was tickled by LegalizeTypes which happened
to legalize the testcase slightly differently to
LegalizeDAG.
