PR32083 - Use correct sign for -Inf in real.c's mpfr_from_real

[Tobias Burnus]

:ADDPATCH middle-end:

This should be obvious. REAL_VALUE_TYPE's sign is one for negative
numbers and zero for positive numbers.
mpfr_set_inf is positive for sign >= 0, and negative for sign < 0.

Build on x86_64-unknown-linux-gnu and checked via check-gcc and
check-gfortran with no new failures.
(failing are gcc.c-torture/execute/mayalias-2.c (ICE),
gcc.c-torture/execute/mayalias-3.c (ICE) and gcc.dg/cpp/Wmissingdirs.c)

Ok for the trunk?

Tobias
