Added a Presentation Compiler test for hyperlinking.

This test ensures hyperlinking works inside and around pattern matching. The new virtual pattern matcher
synthesizes trees that are not properly nested, and whose positions make it impossible to retrieve the correct
tree/symbol for a given position. Therefore, the current test is using the old pattern matcher. However,
once the virtual pattern matcher is fixed, remove the corresponding line from patmat.flags to re-enable virtpatmat.
