This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.

would mean.

(or (x << c) | (y >> (64 - c))) ==> (shld64 x, y, c)

The isel patterns may not catch all the cases if general dag combine has reduced width of source operands.

This lets isel fold loads into them in more cases.

on the example in PR4216.  This doesn't trigger in the testsuite,
so I'd really appreciate someone scrutinizing the logic for
correctness.

multiply sequence when the power is a constant integer.  Before, our
codegen for std::pow(.., int) always turned into a libcall, which was
really inefficient.

This should also make many gfortran programs happier I'd imagine.
