c055a8782e Fix PR11106 by correcting a typo that has been in the code for over a year. This
would have never worked, since the element type of a vector type is never a
vector type. Also fix the conditional to be more direct in checking whether
EltTy is a vector type.

2cf8dd384e ARM addressing mode cleanup for LDC/STC.
We parse at least some forms of the instructions now. Encoding is
pretty screwed up, still, though.

204494149b Move replaceCongruentIVs into SCEVExapander and bias toward "expanded"
IVs.

Indvars previously chose randomly between congruent IVs. Now it will
bias the decision toward IVs that SCEVExpander likes to create. This
was not done to fix any problem, it's just a welcome side effect of
factoring code.

142bd1a54e Move -widen-vmovs to ARMBaseInstrInfo::expandPostRAPseudo().
The VMOVS widening needs to look at the implicit COPY operands.  Trying
to dig out the COPY instruction from an iterator in copyPhysReg() is the
wrong approach.

The expandPostRAPseudo() hook gets to look at COPY instructions before
they are converted to copyPhysReg() calls.

bb5b3f3359 Add a natural stack alignment field to TargetData, and prevent InstCombine from
promoting allocas to preferred alignments that exceed the natural
alignment. This avoids some potentially expensive dynamic stack realignments.

The natural stack alignment is set in target data strings via the "S<size>"
option. Size is in bits and must be a multiple of 8. The natural stack alignment
defaults to "unspecified" (represented by a zero value), and the "unspecified"
value does not prevent any alignment promotions. Target maintainers that care
about avoiding promotions should explicitly add the "S<size>" option to their
target data strings.
