[PATCH] D70404: [ThinLTO] Always import constants

[Eugene Leviant via Phabricator via llvm-commits]

evgeny777 updated this revision to Diff 230454.
evgeny777 added a comment.

I reimplemented the patch, now using extra 'Constant' attribute in GlobalVarSummary.

The goal is to allow importing of constants, which are not being detected as 'ReadOnly'. Such constants are imported with available_externally linkage, still allowing compiler to make some optimizations along the way.
