c21cf2d334 Function calls are handled with a LoadIC and a FunctionCallStub. This works well, but we can create a platform to gather custom feedback by inventing a CallIC. CallIC takes a JSFunction as input, maintains UNINIT/MONO/MEGA state in a feedback slot, and engages in limited patching for the most efficient code. 
The change creates a degrade in NBody tests, but a follow-on CL addresses it by using this custom feedback platform to give a 45% improvement.

e3e7daf01c We need to know if a load, store or call IC is assumed 
to be on the global object. Previously, this information
was stored in RelocInfo. A more logical place for this kind
of structural information is ExtraICState. Storing it there
makes it easier for us to gather type feedback from these
sites too.

2a4be7067c Refactor the compiling pipeline. 
Goals:
 - easier to read, more suitable identifiers.
 - better distinction between compiling optimized/unoptimized code
 - compiler does not install code on the function.
 - easier to add features (e.g. caching optimized code for osr).
 - remove unnecessary code.

e066a3667d Move responsibility for definition of ExtraICState bits into the ICs. 
Currently it's in the Code object for some ICs and in ICs for other ICs.
This should make it easier to alter bits as needed.

2) Recover an extra bit in the code object to give us 6 bits for the extra ic state. We'll need it soon to store contextual state.

3) Cleanup code that treated StrictMode enum and ExtraICState enum as interchangeble.

a4b4cfdc58 HeapProfiler: provide human readable names for code objects. 
It is very hard to understand the structure of the heap even for about:blank page
because code objects in the heap have no names. This patch propagates the names
for Code::STUB and Code::BUILTIN code objects.
Also it assign function names from SharedFunctionInfo to the code objects.

bdeaf7514a Enable preaging of code objects when --optimize-for-size. 
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.
