Trevor Gross cf5eb27910 mbe: Restructure macro_metavar_expr tests
These tests have expanded beyond the RFC, so rename the directory
`rfc-3086-metavar-expr` to `metavar-expressions`. `concat` (which wasn't
part of the RFC) now fits in this group, so merge its tests into the
`metavar-expressions` directory.

Additionally rename some related `issue-*` tests.
