Nadav Rotem 8d80452076 LICM uses AliasSet information to hoist and sink instructions. However, other passes, such as LoopRotate
may invalidate its AliasSet because SSAUpdater does not update the AliasSet properly.
This patch teaches SSAUpdater to notify AliasSet that it made changes.
The testcase in PR12901 is too big to be useful and I could not reduce it to a normal size.

Nadav Rotem 5d4e205874 MemoryDependenceAnalysis attempts to find the first memory dependency for function calls.
Currently, if GetLocation reports that it did not find a valid pointer (this is the case for volatile load/stores),
we ignore the result. This patch adds code to handle the cases where we did not obtain a valid pointer.

Jim Grosbach b4e1ba7191 ARM: Move Thumb2 tests to Thumb2 test file and fix CHECK lines.
These tests weren't actually being run before (missing ':' after CHECK).

Jakob Stoklund Olesen 702bcc3bcf Remove the TII::scheduleTwoAddrSource() hook.
It never does anything when running 'make check', and it get's in the
way of updating live intervals in 2-addr.

The hook was originally added to help form IT blocks in Thumb2 code
before register allocation, but the pass ordering has changed since
then, and we run if-conversion after register allocation now.

When the MI scheduler is enabled, there will be no less than two
schedulers between 2-addr and Thumb2ITBlockPass, so this hook is
unlikely to help anything.

It is still possible to if-convert if the tail block has extra
predecessors, but the tail phis must be rewritten instead of being
removed.

Tim Northover 5aaa7fde94 Use correct loads for vector types during extending-load operations.
Previously, we used VLD1.32 in all cases, however there are both 16 and 64-bit
accesses being selected, so we need to use an appropriate width load in those
cases.

Jakob Stoklund Olesen bc55bfde03 Add a proper if-conversion cost model.
Detect when there is not enough available ILP, so if-conversion can't
speculate instructions for free.

Compute the lengthening of the critical path when inserting a select
instruction that depends on the condition as well as both sides of the
if.

Reject conversions that would stretch the critical path by more than
half a mispredict penalty.

Jakob Stoklund Olesen 3484420927 Add more trace query functions.
Trace::getResourceLength() computes the number of cycles required to
execute the trace when ignoring data dependencies. The number can be
compared to the critical path to estimate the trace ILP.

Trace::getPHIDepth() computes the data dependency depth of a PHI in a
trace successor that isn't necessarily part of the trace.
