Enable passing a RPATH to Swift shared libraries.  This enables testing
libraries before they have been installed.

On Windows, `CollapseFullPath` called with a path that ends with a dot
might return a file with the same base name but any extension.
To make sure we get only the file with the requested header extension,
pass the complete file name to `CollapseFullPath`.

In commit 6e613ff3 (bootstrap: Add infrastructure to detect threading
flags, 2017-11-28, v3.11.0-rc1~281^2~1) an extra level of nesting was
added to the selection loop, but the inner-most `break` command used to
exit the loop on success was not updated.  This caused the outer-most
loop to iterate unnecessarily and repeatedly try the same compilers
again.  In the case of compilers requiring a `-std=` flag, this may have
caused the oldest standard to be used instead of the newest.

Pass the value to the Swift compiler driver via `-sdk`.  We already do
this for C/C++ via `-isysroot`.

This fixes command-line builds on macOS 10.15 with Xcode 11 Swift tools.

`-num-threads` is for the threading, not the job control.  Use `-j` to
launch the parallel jobs.  This enables parallel builds for Swift again
after driver updates preventing the parallelization through
`-num-threads`.

The original intent of <PackageName>_ROOT may have been for it
to apply only to Find modules, but the implementation of the
find_package() command treats modules and config packages the
same. Both result in a <PackageName>_ROOT variable being
pushed onto the stack of package roots. A config package can
also call other find_...() commands, the behavior doesn't apply
just to find modules.

This fixes two errors: not accounting for the trailing null and a
misunderstanding of what std::numeric_limits::digits10 means.

Fix the `COMPILE_LANGUAGE/CXX_COMPILER_ID` variant of the example to
have the same meaning as the `COMPILE_LANG_AND_ID` variant.  The
inconsistency was introduced by commit 808b8180 (Genex: CompileLang
and CompileLangAndId now match against a list of ids, 2019-05-30,
v3.15.0-rc1~11^2~1).

Teach the Makefile generator to scan the implicit dependencies of PCH
creation.  When a header named by `target_precompile_headers` changes
the corresponding PCH must be rebuilt and all consumers recompiled.
