Fixed an issue with looking up line table entries by address where internal
...
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.

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

Be more forgiving when calculating alias interference for physreg coalescing.
...
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.
