Don't leak ISA to __attribute__ ((target("arch=XXX")))
When processing __attribute__ ((target("arch=XXX"))), we should clear
the ISA bits in x_ix86_isa_flags first to avoid leaking ISA from
command line.

* config/i386/i386.c (ix86_valid_target_attribute_tree): If
arch= is set, clear all bits in x_ix86_isa_flags, except for
ISA_64BIT, ABI_64, ABI_X32, and CODE16.
