Allow dllimport/dllexport on inline functions and adjust the linkage.

This is a step towards handling these attributes on classes (PR11170).

Eliminate DefaultImageName from the Driver constructor

All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.

This also brings about the possibility of adapting the value based on the
driver's compatibility mode in future.

The setting can still be changed via Driver::DefaultImageName as needed.

MS ABI: Use musttail for thunk IR generation

This allows us to perfectly forward non-trivial arguments that use
inalloca.

We still can't forward non-trivial arguments through thunks when we have
a covariant return type with a non-trivial adjustment.  This would
require emitting an extra copy, which is non-conforming anyway.

test/CodeGenCXX/dllexport.cpp: we already correctly emit b() even when

InstrProf: Set profile data to visibility hidden

Shared objects are fairly broken for InstrProf right now -- a follow-up
commit in compiler-rt will fix the rest of this.

The main problem here is that at link time, profile data symbols in the
shared object might get used instead of symbols from the main
executable, creating invalid profile data sections.

InstrProf: Look for the PIC-version of the profile runtime

If `-shared` is specified, pull in a PIC-version of the profile runtime,
which was added to compiler-rt in r208947.  I'm hoping this will get the

Update for llvm api change.

Now that llvm cannot represent alias cycles, we have to diagnose erros just
before trying to close the cycle. This degrades the errors a bit. The real
solution is what it was before: if we want to provide good errors for these
cases, we have to be able to find a clang level decl given a mangled name
and produce the error from Sema.

Missed a ! in the if statement when these were being set and the options
are inverted in clang and llvm.

I'll attempt to get a testcase for this that doesn't involve compiling to .s,
but it's unlikely.
