Marco Brambilla 1f164d7ee0 Fix wait fork trigger temporary split across generated functions (#7985) (#7986) 
splitCheck() cuts a function's top level statement list on node count
alone, ignoring AstVar declarations in that list. localizeVars() puts the
dynamic trigger temporaries there, which a 'wait fork' reaches, so the
declaration could land in one sub-function and its references in another.
Sub-functions are emitted as separate C++ functions, so the output failed
to compile:

    error: '__Vtrigprevexpr_h5d9da2ce__0' was not declared in this scope

V3InlineCFuncs could also inline the sub-function holding the declaration
and free the AstVar while other sub-functions still referenced it, which
--debug reports as a broken link and which segfaults an -O3 build.

The existing "Can't split function with local variables" assertion only
checked AstCFunc::varsp(), not declarations among the statements.

Only allow a sub-function boundary where it does not separate a local
declaration from a reference to it. This keeps the temporaries function
local, as #6859 requires, while restoring the guarantee #5822 made that
splitting cannot orphan them.

Geza Lore d58f512a85 Internals: Remove stepCost use in MT scheduling (#8032) 
MT scheduling used to round MTask costs to the nearest 5% to supposedly
reduce the amount of work required for propagating critical path change
updates. Profiling shows this doesn't actually save any verilation time,
as the floating point arithmetic itself is costly, and the propagation
savings only kick in when merging small tasks into large ones, which is
not the common case. (The float arithmetic also made this step
non-reproducible across host architectures and libm versions  due to
numerical variance.)

Remove and use precise costs instead.

Geza Lore 0750e18ad0 Internals: Remove ordering before MTask contraction (#8019) 
As the removed comment suggests, this is dubious and RTLMeter suggests
it makes no measurable difference on average (some designs improve, some
regress small amounts, on average ~1.0x)

Prep for further fixes that will remove the pre ranking.
