Compaction selection now derives target fragmentation based on compaction speed
and a goal per page, if compaction speed has been traced. This way we avoid
overlong compaction of single pages.

This change could regress memory consumption if (a) the memory reducer does not
kick in, and (b) lots of medium fragmented pages would be compacted in our fast
path.

  original commit message:
  Up until now we sometimes pass Smi 0 around as closure and expect the
  runtime to translate that appropriately. But we need to be careful in
  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).

The fast-prototype test has been outsmarted by constructor inlining
because the instantiation is been correctly optimized away. Internal

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.

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.
