ira: Fix elimination for global hard FPs [PR97054]
If the hard frame pointer is being used as a global register,
we should skip the usual handling for eliminations. As the
comment says, the register cannot in that case be eliminated
(or eliminated to) and is already marked live where appropriate.
Doing this removes the duplicate error for gcc.target/i386/pr82673.c.
The “cannot be used in 'asm' here” message is meant to be for asm
statements rather than register asms, and the function that the
error is reported against doesn't use asm.
