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.

Geza Lore c878a7e735 Optimize VL_ONEHOT 
Equivalent to `__builtin_popcount(_) == 1` and a few instructions
shorter.

Geza Lore 7b45b3ee8a Optimize string formatting runtime functions 
Add an overload that takes `const char*` format string. This avoids
having to construct/destruct a temporary `std::string` at the call site
when calling these functions with a string literal, which is fairly
common. This is worth 25% code size on some assertion heavy design.

Also use `std::string::clear()` instead of assigning an empty string
which is more efficient.

Optimize $sformatf into $sformat (#7701) 
Turn `x = $sformatf(...)` into `$sformat(x, ...)`. The former requires
checking and running a destructor for `x` at the call site, the later
does it in the callee VL_SFORMAT. This reduces the size of the call
site, which can be significant e.g. in the presence of many assertions.

Also added a rewrite of `$sformat(x, "const-string")` back into `x =
"const-string"` for the cases where the `$sformatf` would have been
folded into a constant string.

Optimize VL_SFORMAT when result is string (#7702) 
Omit unused bit width parameter. Emit rule is simple enough to change
and the unused parameter just bloats code size.

Optimize $sformat in V3Life (#7703) 
Treat AstSFormat as a special form of assignment in V3Life. This allows
eliminating earlier redundant assignments to strings when an $sformat
later sets the string. UVM has lot of these.

Optimize DPI import argument passing (#7704) 
Pass inputs to DPI import wrappers by reference (unless fits in a
register). This eliminates a lot of temporary constructors/destructors.

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.
