This bug was exposed by my inliner cost changes in r94615, and caused failures

piping through llvm-mc. It will be extended over time as the matcher grows

Preserve load alignment in instcombine transformations. I've been unable to

create a testcase where this matters. The select+load transformation only

instcombine also changes the underlying objects to be aligned. This seems
like a good idea regardless, and I've verified that it doesn't pessimize
the subsequent realignment.

Fix reference binding of const lvalue references to bit-fields, which

sequence that bound to the bit-field as if it were a real lvalue. Note
that we previously (and still) diagnose binding of non-const
references to bit-fields, as we should.
There's no real way to test that this code is correct, since reference
binding does not *currently* have any representation in the AST. This
fix should make it easier for that to happen, so I've verified this
fix with...
Added InitializationSequence::dump(), to print an initialization
sequence for debugging purposes.
