read_frame_register_value and big endian arches

The read_frame_register_value function as it was implemented introduced
a regression on big-endian targets. The problem appears when trying to
get the value of an entity stored inside a register, and when the size
of the entity is smaller than the size of the register. In that case,
we were always reading the first N bytes of the register, which is wrong
for big-endian architectures, where we need to read the last N bytes of
the register.

gdb/ChangeLog:

        * findvar.c (read_frame_register_value): Read correct bytes from
        register on big-endian architectures.

gdb/testsuite/ChangeLog:

        * gdb.ada/small_reg_param: New testcase.

When opening the procfs map file, we create a cleanup routine to make
sure that the associated file descriptor gets closed, but we never
call the cleanup. So the FD gets leaked.

gdb/ChangeLog:

        * procfs.c (iterate_over_mappings): Call do_cleanups before
        returning.

* gdbtypes.c (check_typedef): Document that this function can
