Add support for enums on the match expression
This is our initial first pass of adding support for the MatchExpr though
two things stand out here. We need to switch over to using a GCC enumeral
type for the union qualifier so we get advantage of the GCC code to ensure
all variants are being addressed. We also need to fix out enum type to
get better gdb support which might be simply chaning over to the
qual_union_type.
Fixes #190
