6aa0f72ae9 Silence spurious warning in Verilog lexer when compiling with GCC
The chosen value shouldn't have any effect. I considered something
clearly wrong like -1, but there's no checking inside the generated
lexer, and I suspect this will cause even weirder bugs if triggered
than just setting it to INITIAL.

Add YS_FALLTHROUGH macro to mark case fall-through
C++17 introduced [[fallthrough]], GCC and clang had their own vendored
attributes before that. MSVC doesn't seem to have such a warning at all.
