preprocessed testcase

mpfr tasinh 3.1.1. does not produce correct code for optimization level
-O1 and above. Preprocessed ouput for a reduced testcase is attached.
For the reduced testcase, if-condition at line 45 (original source) is
evaluated true whereas it is not when compiled with -O1 and run. This
can be easily verified with gdb.

gcc version 4.9.0 20130922 (experimental)
