[PATCH v3 12/15] gas: Don't skip SFrame FDE if .cfi_register specifies RA w/o tracking

[Jens Remus <jremus@linux.ibm.com>]

Do not skip SFrame FDE if .cfi_register specifies RA register without
RA tracking being actually used. Without RA tracking the register
contents can always be restored from the stack using the fixed
RA offset from CFA.

gas/
	* gen-sframe.c (sframe_xlate_do_register): Do not skip SFrame
	FDE if .cfi_register specifies RA register without RA tracking
	being used.
