I've applied the following patch to fix a regression in code generation
caused by the fix for PR 20754.  The register allocator was too often
choosing a floating-point register instead of a general register when
a general register.

Tested on hppa2.0w-hp-hpux11.11.  Committed to 4.0 through to trunk.
