[llvm-commits] [PATCH] [lld] Add TargetInfo abstraction.

[Michael Spencer]

Hi shankarke, khemant, kledzik,

This patch adds the TargetInfo abstraction, but doesn't move anything over to use it.

The TargetInfo class is the root source of information for different parts of the linker. The readers, writers, resolver, and passes use this to make choices and perform actions.

In addition to the generic TargetInfo, each file format gets its own TargetInfo type which may have additional functionality specifically needed by that format's reader or writer.
