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.

In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.
