recog: Split out a register_asm_p function
verify_changes has a test for whether a particular hard register
is a user-defined register asm. A later patch needs to test the
same thing, so this patch splits it out into a helper.
gcc/
* rtl.h (register_asm_p): Declare.
* recog.c (verify_changes): Split out the test for whether
a hard register is a register asm to...
* rtlanal.c (register_asm_p): ...this new function.
