adecb5e82c Force the greedy register allocator to always use the inline spiller. 
Soon, RegAllocGreedy will start splitting live ranges, and then deferred
spilling won't work anyway.

276445f3b8 Rip out live range splitting support from the inline spiller. 
The spiller should only spill. The register allocator will drive live range
splitting, it has the needed information about register pressure and
interferences.

4bd64fa805 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.

d29b38c893 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.

0c67e01e5f 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.
