rustc debuginfo test sample #1

1. Compile the attached test file `rustc -g associated-types.rs`.
2. Run `gdb -x dbg.script ./associated-types`, dbg.script as follows:

~~~~
set charset UTF-8
show version
add-auto-load-safe-path /home/infinity0/rustc/./src/etc
set print pretty off
directory /home/infinity0/rustc/./src/etc
file /home/infinity0/rustc/build/armv7-unknown-linux-gnueabihf/test/debuginfo/associated-types.gdb/a
set language rust
break 'associated-types.rs':111
break 'associated-types.rs':118
break 'associated-types.rs':122
break 'associated-types.rs':130
break 'associated-types.rs':137
break 'associated-types.rs':140
run
print arg
continue
print inferred
print explicitly
continue
print arg
continue
print arg
continue
print a
print b
continue
print a
print b
continue
quit

This works for all rustc versions (I was able to test 1.13 - 1.59) on gdb 10 but fails with SIGILL on gdb 11.2 armhf Debian.

Other rustc debuginfo tests fail with other signals, SIGSEGV, SIGABRT, etc. More specific details here: https://github.com/rust-lang/rust/issues/96983
