Watch out for a constant offset cancelling out a base register, forming
...
a zero. This situation arrises in Fortran code with induction variables
that start at 1 instead of 0. This fixes PR7651.

Correctly set rpath on Mac OS X for executable tools. Note that I am not certain this is the best fix; the code immediately above looks confused, as it first checks to see if we are NOT on Darwin and then checks the Darwin version number. This fix allows c-index-test (in Clang) to run outside of running the regression test suite. I would appreciate if someone reviewed this.

Fix PR7647, handling the case when 'To' ends up being

mutated by recursive simplification. This also enhances
ReplaceAndSimplifyAllUses to actually do a real RAUW
at the end of it, which updates any value handles
pointing to "From" to start pointing to "To". This
seems useful for debug info and random other VH users.
