[PATCH] D37059: [ELF] - LTO: do not optimize away symbols accessed from linkerscript.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added subscribers: inglorion, emaste.

Previously when BC file had global variable that was accessed from script,
it was optimized away. 
In this patch I add left side of assignment expression to list of symbols referenced
by script. That marks them used from regular objects for LTO and fixes issue observed.
