[PATCH] [complex] Teach the complex math IR gen to emit direct math and a NaN-test prior to the call to the library function.

[Bill Schmidt]

I realize this revision is closed, but...

Three of these test variants fail in the parser (unsupported floating point type) when compiled for powerpc64le-unknown-linux-gnu:

long double _Complex mul_long_double_cc(long double _Complex a, long double _Complex b)
long double _Complex div_long_double_rc(long double a, long double _Complex b)
long double _Complex div_long_double_cc(long double _Complex a, long double _Complex b)
