[PATCH] D54633: [NFC][AArch64] Split out backend features

[Diogo N. Sampaio via Phabricator via llvm-commits]

dnsampaio updated this revision to Diff 175279.

dnsampaio added a comment.

Fixed:
 the features implications/dependencies.
 the name of the JavaScript conversion feature.
 some test files.

@olista01: Most GCC devs I asked about internal feature names emphatically said that sync of internal names of features is not required. And most of the features are not even visible internally, as they are also associated with architecture reviews. So not much to do about that.

So I tried to make their description as close as possible to the reference manual, as to make it easy to grep for them. Further changes for defining arguments should be straightforward.
