Temporary hack to let codegen assert or generate poor code in case

we are using AVX and no AVX version of the desired intruction is present,
this is better for incremental dev (without fallbacks it's easier to spot
what's missing). Not sure this is the best hack thought (we can also disable
all HasSSE* predicates by dinamically marking them 'false' if AVX is present)

don't visit all blocks in the function, and don't iterate over the split blocks'

LoopSimplify isn't being redundantly run both before and after

- Allow target to specify when is register pressure "too high". In most cases,
...
it's too late to start backing off aggressive latency scheduling when most
of the registers are in use so the threshold should be a bit tighter.
- Correctly handle live out's and extract_subreg etc.
- Enable register pressure aware scheduling by default for hybrid scheduler.
For ARM, this is almost always a win on # of instructions. It's runtime
neutral for most of the tests. But for some kernels with high register
pressure it can be a huge win. e.g. 464.h264ref reduced number of spills by
54 and sped up by 20%.

Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into:
...
mov pc, r1
.align 2
LJTI0_0_0:
.long LBB0_14
This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.

Fix a couple issues with Win64 ABI

1) all registers were spilled as xmm, regardless of actual size
2) win64 abi doesn't do the varargs-size-in-%al thing

xmm6-15 are marked as clobbered by call instructions on win64 even though they aren't.
