Provide a way to specify inliner's attribute compatibility and merging.

This reapplies r256277 with two changes:

- In emitFnAttrCompatCheck, change FuncName's type to std::string to fix
  a use-after-free bug.
- Remove an unnecessary install-local target in lib/IR/Makefile. 

Original commit message for r252949:

Provide a way to specify inliner's attribute compatibility and merging
rules using table-gen. NFC.

This commit adds new classes CompatRule and MergeRule to Attributes.td,
which are used to generate code to check attribute compatibility and
merge attributes of the caller and callee.
