- Add REM token
- Fix checking of function fingerprints.
- Remove unused intrinsic for remainder (the function gets inlined and intrinsic is not generated)

sra@google.com ce4b15c0e9 Esoteric bit operations. 
- bit length
- truncate to signed fixed width integer
- truncate to unsigned fixed width integer

This change is motivated by a program that spends 20-30% of its time here:
    // TODO(5828): Replace this with a bit-length method on int when available.
    int n_bitLength = this.n.toRadixString(2).length;

asiva@google.com dcb6850f87 Fix for issue 11680 
- implicitly store a full stack trace in Error objects when they are thrown.
- the shlFromInt on Mints and Bigints was trying to allocate a new OutOfMemory
  exception objects instead of using the pre-allocated exception object.
  Made the implementation of these methods native so that they can use the
  pre-allocated object.
- Ensure that it is not possible to allocate new OutOfMemory or StackOverflow
  exception objects.

The only remaining thing is that int and double have a pow
method in the VM which is not officially a part of corelib.
Maybe it should be so I have left that out of this change
and maybe we should add it to num and implement in dart2js
too?
