9a488a8317 It's possible that an all-zero GEP may be used as the argument to lifetime
intrinsics. In fact, we'll optimize a bitcast to that when possible. Detect it
when looking for the lifetime intrinsics.

No test case, noticed by inspection.

5e5ed44577 Be less aggressive about hinting in RAFast.
In particular, don't spill dirty registers only to satisfy a hint. It is
not worth it.

The attached test case provides an example where the fast allocator
would spill a register when other registers are available.

b05f14b3b9 Improve the generated code by getCopyFromPartsVector for promoted integer types.

truncate.

testcase).

b95fd2d5fd Tweak hash function and compress hash tables.
Make the hash tables as small as possible while ensuring that all
lookups can be done in less than 8 probes.

Cut the aliases hash table in half by only storing a < b pairs - it
is a symmetric relation.

Use larger multipliers on the initial hash function to ensure that it
properly covers the whole table, and to resolve some clustering in the
very regular ARM register bank.

This reduces the size of most of these tables by 4x - 8x. For instance,
the ARM tables shrink from 48 KB to 8 KB.

4091b059ec Extract the generateHashTable function.
The constant hash tables for sub-registers and overlaps are generated
the same way, so extract a function to generate and print the hash
table.

Also use the information computed by CodeGenRegisters.cpp instead of the
locally data.

4509ec42b8 AnalyzeBranch doesn't change which successors a bb has, just the order
we try to branch to them.

Before we were creating successor lists with duplicated entries. Fixing that
found a bug in isBlockOnlyReachableByFallthrough that would causes it to
return the wrong answer for

026dc223ae Compute lists of sub-regs, super-regs, and overlapping regs.
Besides moving structural computations to CodeGenRegisters.cpp, this
also well-defines the order of these lists:

- Sub-register lists come from a pre-order traversal of the graph
  defined by the SubRegs lists in the .td files.

- Super-register lists are topologically ordered so no register comes
  before any of its sub-registers. When the sub-register graph is not a
  tree, independent super-registers appear in numerical order.

- Lists of overlapping registers are ordered according to register
  number.

This reverses the order of the super-regs lists, but nobody was
depending on that. The previous order of the overlaps lists was odd, and
it may have depended on the precise behavior of std::stable_sort.

The old computations are still there, but will be removed shortly.

9a09ca348f Initialize BasicAA's AliasCache to set it to use fewer buckets by
