Heuristic: If the number of operands in the alias are more than the number of
...
operands in the aliasee, don't print the alias.

Have the X86 back-end emit the alias instead of what's being aliased. In most
...
cases, it's much nicer and more informative reading the alias.

Teach codegen to lower llvm.powi to an efficient (but not optimal)
...
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.
