Optimize runtime assertOn() checks (#7707) 
Combine consecutive assertOn() checks into one, and hoist past enclosing
'if' statements if possible. This enables combining a lot of them, which
can be worth 10% performance on some assertion heavy designs depending
on how the assertions are written.

Optimize wide conditional expansion in V3Premit (#7691) 
V3Premit extracts wide sub-expressions via temporaries, which is needed
for emitting wide operations to C++ (calls to `VL_*_W`). The previous
version used to extract both branches of an AstCond unconditionally,
meaning both branches were fully evaluated. Rewriting the AstCond into
an AstIf instead enables evaluating only the required branch. While
this does limit V3Subst, overall the resulting code is ~3% faster,
and contains ~25% fewer branches on a large design.

Internals: Remove 'VlWide::operator bool()' (#7652) 
This was a fudge to work around using VlWide in `if` conditions without
a `_ != 0` check. That check is actually inserted by V3Width (or an
equivalent reduction), so the offending code was only generated
internally. Hopefully fixed the single instance where this really
happened. (If not, C++ will fail to compile with "cannot convert VlWide
to bool in 'if (__HERE__)'" errors, still better than the old version
which used to silently not do the right test due to incorrect implicit
conversions.)
