Add sp_regnum_from_eax/pc_regnum_from_eax to i386 gdbarch_tdep

Browse Source 
* amd64-tdep.c (amd64_x32_init_abi): Set sp_regnum_from_eax to
	AMD64_RSP_REGNUM and pc_regnum_from_eax to AMD64_RIP_REGNUM.

	* i386-tdep.c (i386_gdbarch_init): Initialize sp_regnum_from_eax
	and pc_regnum_from_eax to -1.  Update SP regnum from
	sp_regnum_from_eax and PC regnum from pc_regnum_from_eax if
	needed.

	* i386-tdep.h (gdbarch_tdep): Add sp_regnum_from_eax and
	pc_regnum_from_eax.
