5a70a2235a arm: fix extension feature disabling
Using e.g.

	.arch_extension simd
	.arch_extension nocrypto

so far results in SIMD support getting disabled, which I can't see being
the purpose of the "no"-prefixed variants of architecture extension
specifications.

Of course it is questionable whether the current, counter intuitive
behavior needs to be retained, and the new behavior perhaps be made work
through e.g. a newly recognized "no-" prefix.

47fc6e36e3 gas/arm: Force output of a data mapping symbol for literal pools
If there is a a trailing align statement in a code section we may
output data padding with a data mapping followed by a code alignment
with a code mapping. The literal pool may then be output with a code
mapping symbol which will cause it to be endian swapped in a big-endian
configuration. When outputting a literal pool make sure that a data
mapping symbol is output in all cases.

62ebcb5cbe gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables.  That's OK, but not best
practice.  tc-ppc.c goes further in implementing its own replacement

on constants.  This patch fixes both of these warts.
