gas: testsuite: add new tests for SFrame unwind info
Earlier these tests were in the same commit as previous which adds the
support in GNU assembler to generate .sframe section from CFI
directives. Splitting this out here for ease of applying and testing.
ChangeLog:

+## ARMv8.3 addded support a new security feature named Pointer Authentication. The
