testsuite: Disable some tests when logging

Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".

Some tests rely on enabling debugging for various components.  With
debugging on, this will be lost to the debug file.

Disable separate tty for mi tests when debugging.  This currently
does not work.

disasm.c should send errors to the stderr instead of the logfile.

Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

gdb/ChangeLog:

	* disasm.c (set_disassembler_options): Send errors to stderr.
