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.
