23a270c6e7 Refactor Math.min/max to be a single HInstruction. 
That allows us to dynamically compute representations and insert appropriate HChange instructions.

b5da7279b1 Introduced TypeFeedbackId and BailoutId types. 
This is a refactoring-only CL which improves the typing of IDs associated with
AST nodes. The interesting parts are in utils.h and ast.h, the rest of the CL
basically follows mechanically.

If we're generating bad code anyway, we might as well crash immediately and at least get a proper backtrace.

6549163a55 Add roundsd instruction to ia32 and use it in optimized Math.floor. 
It is available platforms that have SSE 4.1 and allows us to handle
negative numbers without deoptimization. Before we would deoptimize
on negative inputs to Math.floor. x64 already uses this instruction.

* Change Math.floor unit test to make sure every test case gets
optimized by changing the source code for each test case.

* Fix HIR debug printing for some instructions.

slots.

This patch reclaims some of the unused inobject space by the following method:
 - for each constructor function the first several objects are allocated using the initial 
   ("generous) instance size estimation (this is called 'tracking phase').
 - during the tracking phase map transitions are tracked and actual property counts are collected.
 - at the end of the tracking phase instance sizes in the maps are decreased if necessary
   (starting with the function's initial map and traversing the transition tree).
 - all further allocation use more realistic instance size estimation.

Shrinking generously allocated objects without costly heap traversal is made possible 
by initializing their inobject properties with one_pointer_filler_map (instead of undefined). 

The initial slack for the generous allocation is increased from 2 to 6 which really helps some tests.
