    Fix build failure with macOS bison

    PR gdb/24060 points out a compilation failure of the C, Fortran and Pascal
    parsers when they are built using the macOS system bison.  The bug is a
name
    clash between the VARIABLE token name and the VARIABLE enumerator in
ui-out.h.

    This patch renames VARIABLE in c-exp.y, f-exp.y and p-exp.y to
DOLLAR_VARIABLE
    to avoid the clash.  It also renames similar variables in other .y files so
    that all languages use the same name.
