x86: Add target("general-regs-only") function attribute
is incomplete since it is impossible to call integer intrinsics from
a function with general-regs-only target attribute. We need to add a
general_regs_only function attribute to go with it to mark functions
which use only general purpose registers. When making inlining
decisions on such functions, x86 backend can exclude non-GPR compiler
options. The general_regs_only attribute should be added to all x86
intrinsics which use only general purpose registers.

x86: Move OPTION_MASK_* to i386-common.h
x86: Add general_regs_only function attribute
