gdb/cp-name-parser.y: Eliminate make_empty, use cplus_demangle_fill_component

The demangler exports the cplus_demangle_fill_component function that
clients should use to initialize demangle_component components that
use the "s_binary" union member.  cp-name-parser.y uses it in some
places, via the fill_comp wrapper, but not all.  Several places
instead use a GDB-specific "make_empty" function.  Because this
function does not call any of the demangler "fill" functions, we had
to patch it recently to clear the allocated demangle_component's
"d_printing" field, which is supposedly a "private" demangler field.
To avoid such problems in the future, this commit switches those
places to use "fill_comp" instead, and eliminates the "make_empty"
function.
