Adds a profiling counter to each BytecodeArray object, and adds code to Jump and Return bytecode handlers to update this counter by the size of the jump or the distance from the return to the start of the function. This is more accurate than fullcodegen's approach since it takes forward jumps into account as well as back-edges. Modifies RuntimeProfiler to track ticks for interpreted frames. Currently we use the SharedFunctionInfo::profiler_ticks() instead of adding another to tick field to avoid adding another field to BytecodeArray since SharedFunctionInfo::profiler_ticks() is only used by Crankshaft otherwise so we shouldn't need both for BUG=v8:4689 LOG=N Review URL: https://codereview.chromium.org/1707693003 Cr-Commit-Position: refs/heads/master@{#34166}
