Allocate feedback vectors lazily when the function's interrupt budget has reached a specified threshold. This cl introduces a new field in the ClosureFeedbackCellArray to track the interrupt budget for allocating feedback vectors. Using the interrupt budget on the bytecode array could cause problems when there are closures across native contexts and we may delay allocating feedback vectors in one of them causing unexpected performance cliffs. In the long term we may want to remove interrupt budget from bytecode array and use context specific budget for tiering up decisions as well.

Commit 26c00f4a improved the names of most FAST_* elements kinds in the enum. This patch updates the matching Has*Elements and Is*ElementsKind method names accordingly. - HasFastSmiElements => HasSmiElements - IsFastSmiElementsKind => IsSmiElementsKind - HasFastObjectElements => HasObjectElements - IsFastObjectElementsKind => IsObjectElementsKind - HasFastSmiOrObjectElements => HasSmiOrObjectElements - IsFastSmiOrObjectElementsKind => IsSmiOrObjectElementsKind - HasFastDoubleElements => HasDoubleElements - IsFastDoubleElementsKind => IsDoubleElementsKind - HasFastHoleyElements => HasHoleyElements - IsFastHoleyElementsKind => IsHoleyElementsKind Additionally, FastHoleyElementsUsage is renamed to HoleyElementsUsage.

The current usage of this runtime function is broken as it does not prevent inlining of the affected function but rather bails out from the whole unit of compilation after trying to inline affected functions. This simplifies said runtime function to avoid accidental misuse.

Currently, when a long series of removable simulates are merged, we do this by merging them one by one as we find them. As we merge the value value lists of the simulates, those lists snowball so that we get a quadratic complexity wrt runtime and memory consumption. Instead, we gather simulates that need to be merged, and merge them backwards starting from the last simulate.

Added test cases for various combinations of try/catch/finally with throw in different places. Added a regression directory to the messages tests which is processed by the test runner.

In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
