tic54x fixes

A number of the tic54x tests were failing, and I thought it worth
investigating since the target makes use of a lot of hash tables, and
we've just changed gas hash tables.  It turns out none of the gas
failures were due to hashing.

	* config/tc-tic54x.c (stag_add_field_symbols): Don't free "name"
	in case where it isn't copied.
	* config/tc-tic54x.h (LOCAL_LABELS_FB): Undef.
	* testsuite/gas/tic54x/field.d: Dump section contents and symbols
	rather than disassembling.
	* testsuite/gas/tic54x/set.d: Adjust for newer disassembly.

 	* config/tc-aarch64.c (md_begin): Don't bother checking for
 	out of memory failure from str_htab_create.
