[PATCH] D14775: [FunctionAttrs] Provide a mechanism for adding function attributes from the command line

[James Molloy via llvm-commits]

Hi Akira,

This will be useful whenever functionattrs is run; this includes clang but
not, I think, llc.

I considered adding an option to remove attributes, but I decided against
it. Adding an attribute is easy - attributes are almost never removed
during compilation (apart from inlining). However attributes are regularly
inferred, so I could really make no guarantee about the effectiveness of
removing a function attribute (as it may be re added later!)
