2f7228b80c Generalize the and-icmp-select instcombine further by allowing selects of the form
(x & 2^n) ? 2^m+C : C

we can offset both arms by C to get the "(x & 2^n) ? 2^m : 0" form, optimize the
select to a shift and apply the offset afterwards.

20e3b4b380 Factor the (x & 2^n) ? 2^m : 0 instcombine into its own method and generalize it
to catch cases where n != m with a shift.

f6dff84d4e 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.

3bda29eb4f 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.

4a34cbd2b9 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.

c9672cb8be 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.
