Missed out on reflecting changes to Script object layout in objects-debug.cc.

For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object.

The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

The check for the number og GC's required is now 1 or 2 instead of two to get rig of failures on ARM.

Updated the test to keep the code used by the test in the compilation cache by compiling it in another context. This makes the remaining issue with the eval cache more explicit.

The constant for the return sequence length (JSReturnSequenceLength) was
defined in debug.h. Since this constant are also needed outside the debugger code
I moved them into assembler-xxx.h. Otherwise compiling with debuggersupport=off

We use the fast compiler only for top-level code right now.
When always_fast_compiler is set to true, we compile with
the fast compiler whereever possible.

By default this flag is set to false.

Storing a JSArray in the Script object could cause an indirect reference from the compilation cache to a global object to be created. Now the line ends are only stored as a FixedArrya and when that is needed in JavaScript a JSArray copy is created. Changed some of the JavaScript code to cache the line ends in a local variable for better performance.

Fixes issue 526:

BUG=http://code.google.com/p/v8/issues/detail?id=526

The object literals code in the fast compiler returned an incorrect result 
when getter or setters are defined together with computed properties.

Added a regression test that captures the most reduced version of this
problem. 

Also added a test for object literals with getters/setters and 
prototype properties.

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.

Instead, return an empty context handle so the failure to create a

1) setters might be not on the global object itself, but on its prototypes;
2) if property on one of prototypes is readonly, we could shadow it.

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.
