f2f00d0d09 A cache of MD5 sums of source file contents is now maintained. Cpplint is only invoked for new, changed, and files containing errors from the past lint check run. 
As a result, repetitive presubmit checks now run in a blink of an eye, so we can include it as an obligatory pre-submit check to avoid frequent CB breakages on lint errors.

7a6ebbdd6d Do not crash if a V8 extension fails to compile or throws an exception 
when the code is run.

Instead, return an empty context handle so the failure to create a
context can be handled.

eb4d261e24 Remove the different length string types 
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.

On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

a9d7c378d8 Add logging of callbacks in prof-lazy mode. 
This is needed to show calls to DOM in CPU profiles. I can think
of a better approach like adding specific functions into V8 API
for explicitly providing callback names and modifying bindings codegen
appropriately. My plan is as follows:
 - submit this CL;
 - implement anything I need to process log data and display DOM
   calls in profiles;
 - think again about adding specific functions and modifying bindings
   codegen.

d9d18b30f5 Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions. 
Summary:
This change fixes a performance regression introduced by the special
handling of regular expressions in typeof expressions.
As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer
(vs bleeding edge)

Description:
The macros IS_OBJECT and IS_FUNCTION are frequently used in the 
JS runtime functions. 
By introducing new inlined runtime functions %_IsFunction and %_IsObject
we avoid invoking the more expensive %_ClassOf function plus comparing
its result to a string.

53bee811ad Re-enable using push instructions for syncing the virtual frame. 
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during 
syncing a large SMI constant (unsafe SMIs) in the virtual frame.

The new code for storing unsafe SMI constants does not use an extra temporary 
register. This prevents the compiler from ever having to spill during a 
virutal frame sync operation.

For storing a large SMI constant we previously generated:

  mov ecx, (large_smi & 0x0000ffff)
  xor ecx, (large_smi & 0xffff0000)
  push ecx

we now generate:

  push (large_smi & 0x0000ffff)
  or   [esp], (large_smi & 0xffff0000)

Not using a temporary register avoids spilling within an nvocation 
of VirtualFrame::SyncRange.
