sv.c: Use Perl_fabs rather than hand-coded abs expressions
Same as the commit 644e3ee3290a8de5f7fc90ae85ae5c96a2a00039,
Perl_fabs is usually faster and compacter than hand-coded abs
(conditional negation) on modern environments.

Log Message:
-----------
sv.c: Replace a runtime check with compile-time static assertion
The original code used to check U_V(Perl_fabs(SvNVX(sv))) < (UV)IV_MAX
in runtime, but possibility of failing this check will imply that
such perl configuration is unusable anyway. To make this check never fail,
the first non-preserved integer, which is (1 << NV_PRESERVES_UV_BITS),
is required to be less than (or equal to) IV_MAX, which can be checked
at compile time without runtime overhead.
