Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

This is needed for tests which define internal functions which should not be eliminated.
So far this was not needed because of a hack which prevented whole-module-optimizations for tests.
Swift SVN r22658
As part of this change, allow #line directives to extend to the end of the
file, rather than requiring a reset.
Note that #line regions that start or end within function bodies will not
behave correctly when in delayed parsing modes. This was true before and
after this commit. (#line regions contained entirely within a function and
not within any other #line regions should be fine.)
Swift SVN r20571
This patch extends the syntax with a new #line directive that is inspired
by the homonymous CPP directive. It can be specified in all locations a #if
is legal (Stmt, Decl).
Semantics
---------
#line 42 "file.swift"
This makes diagnostics and debug information behave as if the subsequent
lines came from file.swift+42.
#line // without arguments
This switches back to the main source file and the switches back to the
normal line numbering. Any previous #line directives will result in gaps
in the main file.
Rationale
---------
LLDB and the REPL need this for making expressions that are entered into
the expression evaluator or REPL debugable. For more info see
<rdar://problem/17441710> Need #line directive or something similar so we can enhance the debugging of expressions and REPL
Also, I believe the stdlib would benefit from this and it would allow us
to get rid of the line-directive wrapper script.
