[PATCH] D35619: [ELF] - Introduce multiclass JSEq helper for Options.td

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added a subscriber: emaste.

JSEq helper allows to define `XXX` and `XXX=` options forms easily.
Patch should allow to filter out 'XXX=' options (at least most of) from -help output with
a single line change. And it is itself IMO a nice cleanup.

Patch adds testcases and changes few options behavior,
for example it is possible to use -o/--output x/-output x now,
that is consistent with gold and simplifies options declarations.
