Fangrui Song 789a46f2d7 [CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition 
Summary:
Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults
to -fsemantic-interposition).
Users need to specify -fsemantic-interposition to get semantic
interposition behavior.

Semantic interposition is currently a best-effort feature. There may
still be some cases where it is not handled well.

Simon Atanasyan d5c937b3a3 [mips] Add `short_call` to the set of `long_call/far/near` attributes 
MIPS gcc supports `long_call/far/near` attributes only, but other
targets have the `short_call` attribut, so let's support it for MIPS
for consistency.

Simon Atanasyan 1a116db120 [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.
