live range splitting around loops guided by register pressure.

So far, trySplit() simply prints a lot of debug output.

A MachineLoopRange contains the intervals of slot indexes covered by the blocks
in a loop. This representation of the loop blocks is more efficient to compare
against interfering registers during register coalescing.

fold them down to intrinsics.  This currently only supports signed-addition, but could
be generalized if someone works out the magic constant formulas for other operations.

Fix invalid conversion from "const char *" to "char *" for linux systems. strchr() on darwin returns "char *" so we weren't seeing this issue on MacOSX.

Fixed an error where the thread index was being returned as zero in "uint32_t SBBreakpoint::GetThreadIndex() const" even when it isn't specified. It should be UINT32_MAX to indicate there is no thread index set for the breakpoint (the breakpoint isn't thread specific). Also fixed the ThreadSpec.cpp to use UINT32_MAX instead of -1. Fixed the logging Printf statement in "uint32_t SBBreakpoint::GetThreadIndex() const" to not print the address of the "index" function from <string.h>!

While LLVM's main design is that analysis code shouldn't
go out of its way to understand code which hasn't been

find themselves being called in the middle of transform

packs in a full expression, base type, declaration type, etc., by
highlighting the unexpanded parameter packs and providing their names,
