Update to libmpc version 0.9 which brings the following changes:

- New functions:
   . mpc_set_dc, mpc_set_ldc, mpc_get_dc, mpc_get_ldc for converting
     between mpc type variables and C variables of type double _Complex
     or long double _Complex
   . mpc_sin_cos, computing simultaneously the sine and cosine
 - Speed-ups:
   . mpc_pow_si through binary exponentiation
   . mpc_pow_z when the exponent fits in a long
   . mpc_tan through the use of mpc_sin_cos
 - Bug fixes:
   . trigonometric functions: infinite loop due to overflow for large
     arguments
   . exp: close to infinite loop for argument close to 0
   . sqrt: close to infinite loop for argument close to 1
   . add_si: replaced macro by function, since the macro evaluated the
     same expression twice
 - Logging feature for debugging:
     ./configure --enable-logging
     #include "mpc-log.h" instead of #include "mpc.h"
