[clang] Add support for -fcx-limited-range, #pragma CX_LIMITED_RANGE and -fcx-fortran-rules. (#70244)
This patch adds the #pragma CX_LIMITED_RANGE defined in the C
specification.
It also adds the options -f[no]cx-limited-range and
-f[no]cx-fortran-rules.
-fcx-limited-range enables algebraic formulas for complex multiplication
and division. This option is enabled with -ffast-math.
-fcx-fortran-rules enables algebraic formulas for complex multiplication
and enables Smith’s algorithm for complex division (SMITH, R. L.
Algorithm 116: Complex division. Commun. ACM 5, 8 (1962)).
