Comment out IA32_MISC_ENABLE MSR access - this doesn't exist on AMD.
Need to sort out how arch-specific MSRs will be handled.

- Remove the "a" constraint from main output operand for atomic_cmpset().
- Use "+" modifier for the "expect" because it is also an output (unused).

Use '+' modifier for a memory operand that is both an input and an output.
It was actually done in r86301 but reverted in r150182 because GCC 3.x was
not able to handle it for a memory operand. Apparently, this problem was
fixed in GCC 4.1+ and several contrib sources already rely on this feature.

Use plain store for atomic_store_rel on x86, instead of implicitly
locked xchg instruction. IA32 memory model guarantees that store has
release semantic, since stores cannot pass loads or stores.

Rename an argument from "exp" to "expect" since the former makes FlexeLint
uneasy, in case anybody think it might be exp(3) in libm.

This also makes it consistent with other archs.
