Tom Tromey f097f5ad80 Fix crash in "finish"
PR gdb/28155 notes a crash in "finish" that occurs with a particular
source file compiled by clang.

The bug is the typical gdb problem of a missing call to check_typedef.
clang emits a function whose return type is a typedef to void.
get_return_value asserts that the return type is not void, but the
callers were not using check_typedef first.
