Soon, RegAllocGreedy will start splitting live ranges, and then deferred
spilling won't work anyway.

llvm-svn: 121591

The spiller should only spill. The register allocator will drive live range
splitting, it has the needed information about register pressure and
interferences.

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.

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.

instructions to restore a single register rather than an LDM instruction.

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.
