We can't report negative values using histograms, so we split the data

MIPS64: Removing ic.h from code-stubs.h

Port r23977 (d0cba839)

Original commit message:
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

Class syntax parsing

This implements parsing for ClassExpression and ClassDeclaration.
The runtime is not yet implemented and the value is currently
hard coded to undefined.
