From: Philip Herron <philip.herron@embecosm.com>
This suite of tests has two sections: compile/*.rs and compile/torture/*.rs.
The first section is comprised entirely of dg-compile tests, containing a
mixture of dg-warning and dg-error annotations and some with no annotations,
ensuring the creation of resulting asm output. The second section is the same,
but has tests which are ran with the full torture options, for coverage of test
cases that may have an issue with a specific optimization level.

From: Philip Herron <philip.herron@embecosm.com>
This is similar to the compile/torture/*.rs test cases, but all of these are
dg-execute testcases. They are compiled, linked and executed by default. These
testcases are also compiled with the matrix of torture options.
The only caveat here is that gccrs does not currently support the main shim,
so we have a C-style main function here returning zero which is not proper Rust
code.
