Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h. This
minimizes the files that must be rebuilt when changing the macros
for file N.

fcmp{s,d,q} instructions are supposed to ignore quiet NaN (contrary to
the fcmpe{s,d,q} instructions), but the current code is wrongly setting
the NV exception in that case. Moreover the current code is duplicated:
first the arguments are checked for NaN to generate an exception, and
later in case the comparison is unordered (which can only happens if one
of the argument is a NaN), the same check is done to generate an
exception.
Fix that by calling clear_float_exceptions() followed by
check_ieee_exceptions() as for the other floating point instructions.
Use the _compare_quiet functions for fcmp{s,d,q} and the _compare ones
for fcmpe{s,d,q}. Simplify the flag setting by not clearing a flag that
is set the line just below.
This fix allows the math glibc testsuite to pass.

This reduces the size of the individual translation blocks, since
we only emit a single call for each FOP rather than three. In
addition, clear_float_exceptions expands inline to a single byte store.

Make floating point and VIS ops take a parameter for CPUState instead
of relying on global env.

Move FPU op helpers to fop_helper.c. Move VIS op helpers to vis_helper.c,
compile it only for Sparc64.
