Subject: [PR target/16888] clear reg names of unavailable regs
We used to crash at print_operand time, because the register asm
variable named a REX register, not available in 32-bit mode.
This patch arranges for us to clear the names of registers not
available for the given command-line options or defaults, which gets
us an error message at the point of the register var declaration.
An alternative would be to introduce a new target hook to validate
register names, but this didn't sound worth the effort.
Bootstrapped and regtested on amd64-linux-gnu. Ok to install?
