re PR target/19653 (x87 reg allocated for constants for -mfpmath=sse)

PR target/19653
* regclass.c (struct reg_pref): Update documentation.
(regclass): Set prefclass to NO_REGS if memory is the best option.
(record_reg_classes): Cope with a prefclass set to NO_REGS.
* reload.c (find_reloads): Take PREFERRED_OUTPUT_RELOAD_CLASS
into account. For non-registers, equate an empty preferred
reload class to a `!' in the constraint; move the if clause to
do so after those that reject the insn.
(push_reload): Allow PREFERRED_*_RELOAD_CLASS to liberally
return NO_REGS.
(find_dummy_reload): Likewise.
* doc/tm.texi (Register Classes): Document what it means
if PREFERRED_*_RELOAD_CLASS return NO_REGS.
* config/i386/i386.c (ix86_preferred_reload_class): Force
using SSE registers (and return NO_REGS for floating-point
constants) if math is done with SSE.
(ix86_preferred_output_reload_class): New.
* config/i386/i386-protos.h (ix86_preferred_output_reload_class): New.
* config/i386/i386.h (PREFERRED_OUTPUT_RELOAD_CLASS): New.
* config/i386/i386.md: Remove # register preferences.
