[PPC]: Peephole optimize small accesss to aligned globals.
Access to aligned globals gives us a chance to peephole optimize nonzero
offsets. If a struct is 4 byte aligned, then accesses to bytes 0-3 won't
overflow the available displacement. For example:
addis 3, 2, b4v@toc@ha
addi 4, 3, b4v@toc@l
lbz 5, b4v@toc@l(3) ; This is the result of the current peephole
lbz 6, 1(4) ; optimizer
lbz 7, 2(4)
lbz 8, 3(4)
If b4v is 4-byte aligned, we can skip using register 4 because we know
that b4v@toc@l+{1,2,3} won't overflow 32K, and instead generate:
addis 3, 2, b4v@toc@ha
lbz 4, b4v@toc@l(3)
lbz 5, b4v@toc@l+1(3)
lbz 6, b4v@toc@l+2(3)

Larger alignments allow larger structures/arrays to be optimized.

Verifier: Avoid quadratic checking of aggregates for bad bitcasts
Avoid O(N^2) behaviour when checking for bad bitcasts in `ConstantExpr`s

- centralized the "visited" set for recursing through `ConstantExpr`s so
that expressions are only visited once per Verifier run,
- removed the duplicate logic for the stack visit, and
- avoided recursing into other `GlobalValue`s.
This recovers roughly a 100x time difference in clang compiles of a
particular input file (filled with large cross-referencing tables) that
depends on whether `-disable-llvm-verifier` is on. This slowdown was
caused by r187506, which introduced these checks.
Now, avoiding `-disable-llvm-verifier` only causes a 2x slowdown for

[DeadStoreElimination] Add support for non-local DSE.
We extend the search for redundant stores to predecessor blocks that
unconditionally lead to the block BB with the current store instruction. That
also includes single-block loops that unconditionally lead to BB, and
if-then-else blocks where then- and else-blocks unconditionally lead to BB.

Bitcasts between FP and INT values using direct moves
This patch corresponds to review:
http://reviews.llvm.org/D15286
LLVM IR frequently contains bitcast operations between floating point and
integer values of the same width. Doing this through memory operations is
quite expensive on PPC. This patch allows the use of direct register moves
between FPRs and GPRs for lowering bitcasts.

LAA uses the PredicatedScalarEvolution interface, so it can produce
