Rename enableDedicatedDictSearch to dedicatedDictSearch in MatchState
...
This makes it clear that not only is the feature allowed here, we're actually
using it, as opposed to the CCtxParam field, in which it's enabled, but we may
or may not be using it.

The unused function definitions are hidden behind a

Initially hiding all functions which are unused and take up more than
2KB of stack space, because these will show up as warnings in the

Previously, this construct would add `-O3` onto the end of the compiler flags
variable, **after** `MOREFLAGS`, which meant that it was impossible to over-
ride. This commit fixes this order and should otherwise be a no-op.
