Make tuning of hgcd and gcd take hgcd2 choice into account
* gmp-impl.h (hgcd2_func_t) [TUNE_PROGRAM_BUILD]: New typedef.
(hgcd2_func) [TUNE_PROGRAM_BUILD]: New function pointer.
* tune/hgcd2.c (mpn_hgcd2): New file, with a redefined function to
invoke an implementation via the hgcd2_func function pointer.
Initially points to the default implementation in
mpn/generic/hgcd2.c.
* tune/Makefile.am (tuneup_SOURCES): Add hgcd2.c.
* tune/tuneup.c (one_method): Return index of selected function.
(tune_hgcd2): Set hgcd2_func to point to selected function. So
that the later tuning of mpn_hgcd and mpn_gcd uses the right
implementation of hgcd2.
