[PATCH] testsuite: Add support for Rust and Modula-2 effective target tests

[Jakub Jelinek <jakub@redhat.com>]

Hi!

This patch allows magic comments also for Rust and Modula-2
for effective target tests etc. and fixes up the Assembly entry
- it is a glob, so /* Assembly can match /whatever Assembly and
not just /* Assembly.

Tested on x86_64-linux with
make check-g++ RUNTESTFLAGS=i386.exp=pr35513*
and verifying it still uses *.S extension for the property_1_needed
effective target test.

Ok for trunk?
