This creates a nice stub for further sorts of lit based build system unit tests, such as for making sure that debug info is emitted in the correct places.

# This test makes sure that if lto is enabled:
|
|
#
|
|
# 1. We have lto object files for swift in our build tree. We swift and libswiftdemangle.
|
|
# 2. These lto output files all have line tables in the swift include directory,
|
|
# but do not have full debug info. To check for the latter case, we look for
|
|
# SmallVector a commonly used data type.
|
|
# 3. We use swift-demangle since it is a much smaller executable than all of
|
|
# swift.
