  Up until now we sometimes pass Smi 0 around as closure and expect the

  some places to not confuse the Smi 0 with a real closure. However, we
  could instead just pass the correct closure extracted from the native

  This addresses three long-standing TODOs in the JSTypedLowering pass.

  Drive-by-fix: Further unify error message reporting for ToObject (we had
  a special message in case of ToObject error in with context creation).

Decouple the implicit ToObject for with statements from the actual
creation of the with context. This way we can handle/optimize those
constructs separately.

The fast-prototype test has been outsmarted by constructor inlining
because the instantiation is been correctly optimized away. Internal
state introspection about prototype turning fast was upset by that.

This adapts the constructor call inlining machinery to only allocate
implicit receivers and perform the return value check if the callee

This removes an optimization in the static JSFunction visitor that
eagerly marked through to the SharedFunctionInfo for code flushing
candidates. This causes all processing in VisitJSFunction to be
side-stepped and hence might cause leaks.

For a * b with only truncated word32 uses (or result known to be in
signed32 range), we can use Int32Mul if we know for sure that the
intermediate result is inside the safe integer range, and a and b are
in signed32 range.

Drive-by-fix: Also use TypeCache in SimplifiedLowering.

The TruncateFloat32ToInt64 operator converts a float32 to an int64 using
the round-to-zero rounding mode (truncate). If the input value is
outside the int64 range, then the result depends on the architecture. I
implemented the operator on x64, arm64, and mips64.
