tfile.exp: Test printing a non-const global that is not covered by the trace frame; test disassembling.
Make sure we don't fallback to printing the initial value of a
non-const variable in the executable.
Also make sure we can do 'disassemble', as another test that GDB is
able to read read-only parts from the executable (the existing test of
printing constglob also covers that case).

* gdb.trace/tfile.c: Add comments.
(nonconstglob): New global.
* gdb.trace/tfile.exp: Add comments. Test printing a non-const
global that is not covered by the trace frame. Test
disassembling.
