As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias
(movzx/movsx) because they give more information. Revert that part of the patch.

Have the X86 back-end emit the alias instead of what's being aliased. In most
cases, it's much nicer and more informative reading the alias.

Fix fast-isel address mode folding to avoid folding instructions
outside of the current basic block. This fixes PR9500, rdar://9156159.

reapply my fix for PR8961 with a tweak to properly handle
multi-instruction sequences like calls. Many thanks to Jakob for
finding a testcase.

fix PR8961 - a fast isel miscompilation where we'd insert a new instruction
after sext's generated for addressing that got folded. Previously we compiled
test5 into:
_test5: ## @test5
## BB#0:
movq -8(%rsp), %rax ## 8-byte Reload
movq (%rdi,%rax), %rdi
addq %rdx, %rdi
movslq %esi, %rax
movq %rax, -8(%rsp) ## 8-byte Spill
movq %rdi, %rax
ret
which is insane and wrong. Now we produce:
_test5: ## @test5
## BB#0:
movslq %esi, %rax
movq (%rdi,%rax), %rax
addq %rdx, %rax
ret

Use the source-order scheduler instead of the "fast" scheduler at -O0,
because it's more likely to keep debug line information in its original
order.

Add X86FastISel support for return statements. This entails refactoring
a bunch of stuff, to allow the target-independent calling convention
logic to be employed.
