a9db129730 Don't merge uses when they are targetting fixup sites with 
different widths. In a use with a narrower fixup, formulae
may be wider than the fixup, in which case the high bits
aren't necessarily meaningful, so it isn't safe to reuse
them for uses with wider fixups.

This fixes PR7618, though the testcase is too large for a
reasonable regression test, since it heavily dependes on
hitting LSR's heuristics in a certain way.

d1c58cf7bb fix the encoding of MMX_MOVFR642Qrr, it starts with 0xF2 not 0xF3, 
this fixes rdar://8192860.  Unfortunately it can only be triggered
with llc because llvm-mc matches another (correctly encoded) version
of this, so no testcase.

f53462d2ea Teach ScalarEvolution how to fold trunc(undef) and anyext(undef) to undef. 
This helps LSR behave more consistently on bugpoint-reduced testcases.

40bf5e7a68 Per Chris' suggestion, get rid of the select canonicalization and just add 
the corresponding or-icmp-and pattern.  This has the added benefit of doing
the matching earlier, and thus being less susceptible to being confused by
earlier transforms.

d634bcbc89 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.

d2bfe54b0a 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.

35a939b97d make various clients of ReplaceAndSimplifyAllUses tolerate 
it *changing* the things it replaces, not just causing them
to drop to null.  There is no functionality change yet, but 
this is required for a subsequent patch.
