Matt Pharr cc86e4a7d2 Disable coalescing optimizations when using generic target. ...

The main issue is that they end up generating a number of smaller
vector ops (e.g. 4-wide and 8-wide on the 16-wide generic target,
which the examples/intrinsics implementations don't currently
support.

This fixes a number of failing tests for now; it may be worth
generalizing the stuff in examples/intrinsics at some point,
since as a general principle, e.g. if generating LLVM IR output,
the coalescing optimizations are still desirable.

Issue #175.
