where the step value is an induction variable from an outer loop, to
avoid trouble trying to re-expand such expressions. This effectively
hides such expressions from indvars and lsr, which prevents them
from getting into trouble.

the local block. Resolve references to those indices to a new base register.
For simplification and testing purposes, a new virtual base register is
allocated for each frame index being resolved. The result is truly horrible,
but correct, code that's good for exercising the new code paths.

Next up is adding thumb1 support, which should be very simple. Following that
will be adding base register re-use and implementing a reasonable ARM
heuristic for when a virtual base register should be generated at all.

CrashRecovery: Clear the current context on the first crash, to avoid re-entering it if the cleanup code crashes.

CrashRecovery: Add CrashRecoveryContext::GetCurrent(), so clients can find the active context from anywhere.

PHI elimination shouldn't require machineloopinfo since it's used at -O0. Move the requirement to LiveIntervalAnalysis instead. Note this does not change the number of times machineloopinfo is computed.

Fix horrible CFG bug caused by a series of NullStmts appearing at the beginning of a do...while loop.  This would cause
the body of the DoStmt to be disconnected from the preceding code.

CFGBuilder: don't create the empty "loop back" block for DoStmts if the loop edge can never be taken.
