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.

Bill Wendling 706469b453 Add more of the command line options as attribute flags. 
These can be easily queried by the back-end.

Anna Zaks 0f424b029b Revert "Add more attributes from the command line to functions." 
This reverts commit 176009.

The commit is a likely cause of several buildbot failures.

Bill Wendling 87869db5f5 Add more attributes from the command line to functions. 
This is an ongoing process. Any command line option which a back-end cares about
should be added here.

Bill Wendling 985d1c5d15 Add the 'target-cpu' and 'target-features' attributes to functions. 
The back-end will use these values to reconfigure code generation for different
features.

Ulrich Weigand 35668cc401 A number of test cases assume that an "int" parameter or return value 
will be represented in the IR as a plain "i32" type.  This causes the
tests to spuriously fail on platforms where int is not a 32-bit type,
or where the ABI requires attributes like "signext" or "zeroext" to
be used.

This patch adds -triple or -target parameters to force those tests
to use the i386-unknown-unknown target.

Eric Christopher bf005ecd9c 'pure' and 'const' functions should also be marked nounwind. Migrate 
test over from llvm/test/FrontendC++ and update others to account for
the change.
