Do not use function locals in SenExprBuilder (#5822) 
Function locals are not safe here because we might need to split up
the generated function. V3Localize can fix them later if safe.

Fix dynamic NBAs with automatic vars (#4696) 
This patch addresses two issues with NBAs in non-inlined functions/tasks:
- If the NBA writes to a local automatic var, the var could cease to exist before the NBA executes. This is normally addressed by fork dynscopes (#4356), but NBA-to-fork transformation happens way after `V3Fork` (in `V3Timing`). To solve this, we put NBAs that write to locals under forks in `V3Fork` already. This way, such locals will be put in dynscopes, and will still exist after the task containing the NBA exits.
- The above change means that any writes in forks other than `fork..join` should be handled by `V3Fork`. Thus, in `V3SchedTiming`, we only have to worry about read references, so we can simply copy all remaining locals. Because we copy, lifetimes are not an issue. This fixes a bug that allowed assignment intravals to be overwritten if they go out of scope in the containing function.

Delete AstNode user5 (#4638) 
This saves about 5% memory. V3AstUserAllocator is appropriate for most use
cases, performance is marginally up as we are mostly D-cache bound on
large designs.

Fix multiple edge timing controls in class methods (#4318) (#4320) (#4344) 
Multiple edge timing controls in class methods would cause compilation errors on
the generated C++ code. This is because the `SenExprBuilder` used for these
would get recreated per timing control, resulting in duplicate variable names.
The fix is to have a single `SenExprBuilder` per scope.
