Further code clean-up (and consistency) based on icc warnings:

  * Removed useless code.
  * Avoid hiding variable declarations.
  * Use #ifdef BOOL_MACRO instead of #if BOOL_MACRO.
  * In MPFR_RNDRAW_GEN macro definition, variables declared locally now
    start with an underscore to avoid possible conflits with parameters
    (and modified macro calls that use these variables).
