Fix casts in RegionStore to not always assume that bindings are only to SubRegions.  Fixes assertion failure
reported in PR 7572.

line table entries that were termination entries (ones that define the bounds
of the previous entry) could be found when looking up line table entries.
We now properly skip these termination entries and check the next entry to
try for a match.

INSERT_SUBREG will now only appear in SSA machine instructions.

Fix the handling of partial redefs in ProcessImplicitDefs. This is now relevant
since partial redef COPY instructions appear.

This means that an instruction defining an S register will affect the domain of
the parent D register.

Add a new path-sensitive checker for functions in <string.h>, for both null-terminated strings and memory blocks. Currently only checks memcpy(), memmove(), and bcopy(), but this is intended to be expanded soon.

Fix up a few little cases where we weren't reporting command lookup errors correctly.

Added "b" as an alias for "breakpoint" so it doesn't collide with "bt".

Added a path-sensitive idempotent operation checker (-analyzer-idempotent-operation). Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect.

Example:
{
int a = 1;
int b = 5;
int c = b / a; // a is 1 on all paths
}

- New IdempotentOperationChecker class
- Moved recursive Stmt functions in r107675 to IdempotentOperationChecker
- Minor refactoring of SVal to allow checking for any integer
- Added command line option for check
- Added basic test cases

It is OK for an alias live range to overlap if there is a copy to or from the
physical register. CoalescerPair can work out if the copy is coalescable
independently of the alias.

This means that we can join with the actual destination interval instead of
using the getOrigDstReg() hack. It is no longer necessary to merge clobber
ranges into subregisters.
