eca35b76ce When inserting expressions for post-increment users which contain 
loop-variant components, adds must be inserted after the increment.
Keep track of the increment position for this case, and insert
these adds in the correct location.

operands exceeds the number of registers used in the initial
solution, as that wouldn't lead to a profitable solution anyway.

839a0159c4 It turns out that this #include is needed because otherwise 
ValueMapper.cpp ends up calling an out of line 
__ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
determines arbitrarily to use the one in libipo.  This sucks, but
keeping the #include is a reasonable workaround.

c37e3d5d7c When re-using an existing cast for a user, it's still necessary to call 
rememberInstruction so that future users of that user will be inserted
in the correct position. This fixes the Darwin selfhost.

401f3258f6 Fix a crasher trying to fold each element in a comparison between two vectors 
if one of the vectors didn't have elements (such as undef). Fixes PR 6096.

Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would
have <2 x i1> type if constant folding was successful and i1 type if it wasn't.
This exposed a related issue in the bitcode reader.

a10756ee65 Re-implement the main strength-reduction portion of LoopStrengthReduction. 
This new version is much more aggressive about doing "full" reduction in
cases where it reduces register pressure, and also more aggressive about
rewriting induction variables to count down (or up) to zero when doing so
reduces register pressure.

It currently uses fairly simplistic algorithms for finding reuse
opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.
