[SR-1192] LLDB swig static binding failure on non-Apple builds about llvm-project HOT 7 CLOSED

I have temporarily made a manual edit to the static swig bindings until I can adjust the swig step to make sure the #ifdef in the typemap passes through to the generated file.

That temporary change is here:
apple/swift-lldb@fbbacbd

from llvm-project.

It looks like I can use the following swig syntax to support ensuring the #ifdef carries through to the baked file:

From the Swig manual:
```
%{
#ifdef NEED_BLAH
int blah() {
...
}
#endif
%}
```

from llvm-project.

Testing a change for this locally. I'll send up in a PR if this generates the code I expect.

from llvm-project.

Oops no that's not the right syntax.

It looks like I really want:
%#ifdef ...

from llvm-project.

I've got the fix in upstream llvm.org svn trunk. I'm waiting on testing of SR-1193 to complete before I submit a PR for this in GitHub.

from llvm-project.

Testing the PR for this now:
apple/swift-lldb#13

from llvm-project.

Merged in here:
apple/swift-lldb@70cbf39
