Dan Gohman 9ca025f1dc Assigning an APInt to 0 with plain assignment gives it a one-bit
size. Initialize these APInts to properly-sized zero values.

Dan Gohman e1d9ee66ed Simplify some logic in ComputeMaskedBits. And change ComputeMaskedBits
to pass the mask APInt by value, not by reference.

Chris Lattner f6518cf4ab don't try to avoid inserting loads when lowering FORMAL_ARGUMENTS.
DAGCombine is now quite good at zapifying them.

Dan Gohman f990faf23b Convert SelectionDAG::ComputeMaskedBits to use APInt instead of uint64_t.
Add an overload that supports the uint64_t interface for use by clients
that haven't been updated yet.

Evan Cheng 3b3286d4bc It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

Dale Johannesen 36c2967d89 64-bit (MMX) vectors do not need restrictive alignment.
128-bit vectors need it only when SSE is on.

Dan Gohman 16d4bc3dc0 Follow Chris' suggestion; change the PseudoSourceValue accessors
to return pointers instead of references, since this is always what
is needed.

Evan Cheng a20a773654 Fix a x86-64 codegen deficiency. Allow gv + offset when using rip addressing mode.
Before:
_main:
        subq    $8, %rsp
        leaq    _X(%rip), %rax
        movsd   8(%rax), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret
Now:
_main:
        subq    $8, %rsp
        movsd   _X+8(%rip), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret

Notice there is another idiotic codegen issue that needs to be fixed asap:
xorl    %ecx, %ecx
movl    %ecx, %eax

Dan Gohman 2d489b5081 Re-apply the memory operand changes, with a fix for the static
initializer problem, a minor tweak to the way the
DAGISelEmitter finds load/store nodes, and a renaming of the
new PseudoSourceValue objects.

Evan Cheng 2cb9068c78 Dwarf requires variable entries to be in the source order. Right now, since we are recording variable information at isel time this means parameters would appear in the reverse order. The short term fix is to issue recordVariable() at asm printing time instead.
