[PATCH 1/2] gdb: simplify code in check_typedef

Simplify a code portion in check_typedef where the conditions are
unnecessary.  Also remove the comment that says "treat address spaces
and address classes separately", because since the commit 92fdad7
"gdb: convert type instance flags to bitfields", they are separate
fields; so, the comment does not look useful.
