Summary:
GetSVN.cmake currently takes one or two pairs of <source directory path,
name>, then attempts to get the remote repository URL and source control
revision of the repositories at those one or two paths.
It takes two pairs in order for Clang to get the revision of both
itself, and its dependency LLVM.
For projects that rely upon both LLVM and Clang (Apple's Swift is one
example, but there are others), GetSVN.cmake is used to fetch *three*
revisions: Swift, Clang, and LLVM.
To support this use case, change GetSVN.cmake: instead of taking one or
two pairs (specified via `FIRST_SOURCE_DIR`/`FIRST_NAME`, have it take a list
of pairs (`SOURCE_DIRS`/`NAMES`).
In order to allow Clang to migrate, have GetSVN.cmake support both sets
of arguments for now. The old arguments can be removed once Clang begins
using the new arguments, and Swift can follow when it updates its
copy of LLVM.
Test Plan:
1. Perform a clean build of Clang, verify that `clang --version` still
prints the correct LLVM and Clang revision information.
2. Modify Clang's CMake to use the new arguments, then perform another
clean build. `clang --version` should still print the correct
revision information.

This lets the queries work on Windows as well as Linux.
This does mean make and cmake aren't using the same scripts to do the
queries (again), but at least GetSVN.cmake understands git and git-svn
as well as svn now.

This allows the logic to work with Git, and also uses the variable names
to match what Clang is actually looking for.
This is a re-application of r190556 and r190808. This changes the interface
of GetSVN.cmake. Clang change to follow.

I got a report of a hang in git's helper functions trying to figure out
how to display results of "git svn info" when run inside ninja, even though
the result is immediately piped to grep. This seems to avoid that.
