cmd/compile: remove dead flags

Browse Source 
For some time now, the -d flag has been used to control various named
debug options, rather than setting Debug['d']. Consequently, that
means dflag() always returns false, which means the -y flag is also
useless.

Similarly, Debug['L'] is never used anywhere, so the -L flag can be
dropped too.
