Reviewers: Kevin Millikin,

Message:
This only works on IA32 so far, but I wanted to get a first round of reviews
before I start porting it to other architectures.

Description:
Implement target cache for constructor calls.

This caches call targets of constructor calls by embedding a one element
cache into the instruction stream. The type feedback oracle can use the
recorded value to gather type information for monomorphic constructor
call sites.
