Fix incorrect register conflict detection in asm!
...
This would previously incorrectly reject two subregisters that were
distinct but part of the same larger register, for example `al` and
`ah`.

Remove unnecessary check for registers
...
`is_clobber()` already checks if `reg` is a register and the both

Add clobber-only register classes for asm!

These are needed to properly express a function call ABI using a clobber
list, even though we don't support passing actual values into/out of
these registers.
