Currently, feedback vectors are allocated on a fixed budget of 1024. In some cases it might be beneficial to allocate feedback vectors based on invocation count rather than fixed budget. For example, if we have a large function that is only run once. This cl adds an option to use interrupt budget based on the bytecode size. It kind of mimics invocation count. We would allocate feedback vectors early when we have loops which is also required. This flag is turned off by default. In followup cl, we will enable it and if the memory / performance tradeoff is good we might make it default.

Removes the --ignition flag which is now on by default. Adds a --stress-fullcodegen flag which enables running all functions supported by fullcodegen to be compiled by fullcodegen. This will enable moving parser internalization later when we are not stressing fullcodegen or compiling asm.js functions.

1. Replaces --crankshaft with --opt in tests. 2. Also fixes presubmit to check for --opt flag when assertOptimized is used. 3. Updates testrunner/local/variants.py and v8_foozie.py to use --opt flag. This would mean, nooptimize variant means there are no optimizations. Not even with %OptimizeFunctionOnNextCall.

Do not change environment between simulate and scope with no observable side-effects in HandlePropertyAssignment. LChunkBuilder reconstructs the environment by applying simulates. A scope with no observable side-effects has no simulates. If the scope deoptimizes, then LChunkBuilder would miss the changes to the environment between the last simulate and the scope.

report the exception when they happen in the try block and not as previously when re-thrown after execution of the finally block. There is no longer any message generated by re-throw. 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
