[COMMITTED 03/43] gccrs: Add new test cases for old issues

[arthur . cohen]

From: Yap Zhi Heng <yapz...@gmail.com>

rust-GCC/gccrs#3555, rust-GCC/gccrs#3591, rust-GCC/gccrs#3597,
rust-GCC/gccrs#3651, rust-GCC/gccrs#3670 & rust-GCC/gccrs#3672 were all
fixed long ago by some of my older patches, adding test cases to conclude
the issues properly.

gcc/testsuite/ChangeLog:

        * rust/compile/issue-3555.rs: New test case.
        * rust/compile/issue-3591.rs: New test case.
        * rust/compile/issue-3597.rs: New test case.
        * rust/compile/issue-3651.rs: New test case.
        * rust/compile/issue-3670.rs: New test case.
        * rust/compile/issue-3672.rs: New test case.
