    c_value_print: Revert 'val' to a reference for TYPE_CODE_STRUCT

    Currently c_value_print will turn struct reference values into pointers
before
    doing a set of RTTI checks.  This was introduced as a fix to PR c++/15401.
    If there's RTTI the pointer will be adjusted and converted back to a
reference.
    However, if there's no RTTI the value will still be treated as a pointer
during
    the remainder of the function.
    This patch moves the conversion down so that it's always performed when
needed.

    Notice this currently has not user-visible effects, so can be seen as a
small
    code cleanup.  However, it'll be necessary for the bug-fix for handling
    synthetic C++ references.  It causes no testsuite regressions.

    gdb/ChangeLog:
    2016-04-26  Martin Galvan  <martin.galvan@tallertechnologies.com>

        * c-valprint.c (c_value_print): Always convert val back to reference
        type if we converted it to a pointer type.
