`module.map` as a module map name has been discouraged since 2014, and
Clang will soon warn on its usage. This patch renames all instances of
`module.map` in the Swift tests to `module.modulemap` in preparation
for this change to Clang.

Add an additional case to `CallbackCondition` to
support boolean checks, and add the necessary
classification logic to determine whether a bool
flag check is for a success or failure path.
The logic currently first checks to see if the
async alternative has a convention that specifies
which parameter the flag is, and whether it's a
success or failure flag. If so, it classifies the
flag check accordingly. If there's no async
convention specified, we use a heuristic to see if
the error parameter is force unwrapped in the
failure block. If so, we treat that as the error
path. If there's no force unwrap of the error, we
leave the condition unhandled.
