[PATCH] D35479: [CodeGen][mips] Support `long_call/far/near` attributes

This patch adds support for the `long_call`, `far`, and `near` attributes for MIPS targets. The `long_call` and `far` attributes are synonyms. All these attributes override `-mlong-calls` / `-mno-long-calls` command line options for particular function.

      

The main non-trivial part is the change in `CodeGenModule::ConstructAttributeList` routine. It is not enough to configure attributes in `MIPSTargetCodeGenInfo::setTargetAttributes` because this method applied to the function definitions only while we need to configure the attributes for function declarations as well.
