9d1f5ce1da Introduce a new PartialAlias response for AliasAnalysis. For most 
AliasAnalysis consumers, PartialAlias will be treated as MayAlias.

For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
PartialAlias will be used to indicate that the query should terminate,
even though it didn't reach MustAlias or NoAlias.

5ff13f9d5c Fix some invalid alignments for Neon vld-dup and vld/st-lane instructions. 
Alignments smaller than the total size of the memory being loaded or stored,
unless the alignment is 8 bytes, are not allowed.  Add tests for this, too.

e3924a3c85 Add an AllocationOrder class that can iterate over the allocatable physical 
registers for a given virtual register.

Reserved registers are filtered from the allocation order, and any valid hint is
returned as the first suggestion.

For target dependent hints, a number of arcane target hooks are invoked.

2bb1326bb6 Use GZIPBIN instead of GZIP. Apparently gzip uses GZIP as an environment 
variable for args you want to default pass to gzip.

Patch based on one by asau@inbox.ru.

Fixes PR8758.

cb6d1c8193 Formalize the notion that AVX and SSE are non-overlapping extensions from the compiler's point of view. Per email discussion, we either want to always use VEX-prefixed instructions or never use them, and are taking "HasAVX" to mean "Always use VEX". Passing -mattr=-avx,+sse42 should serve to restore legacy SSE support when desirable.

4be3b6db5c Use the new IsAligned fixup flag to improve fixup encodings for Thumb2 branches. This is still not perfect, 
but it gets many more of them correct than it did previously.
