[PATCH] D38239: [ELF] - Prefetch linkerscript symbols.

[George Rimar via Phabricator via llvm-commits]

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

Currently symbols assigned or created by linkerscript are not processed early
enough. As a result it is not possible to version them or assign any other flags/properties.

Patch adds `prefetchSymbols()` method to script class. That allows to set `CanInline` for them,
as a result code is slightly simplified, and also it makes possible to version these symbols properly (
so change is useful for https://reviews.llvm.org/D37731/https://reviews.llvm.org/D36579 patches).
