The only difference between GetNextUncompiledFunctionId + CompileAndSchedule and FetchAndExecuteCompilationUnit is that FetchAndExecuteCompilationUnit potentially calls a callback if it detects that no finishing task is executing. With this CL I replace the two functions again with FetchAndExecuteCompilationUnit. I add a flag so that no callback is called when the flag is not set. If no callback is called, FetchAndExecuteCompilationUnit behaves exactly the same as the other two functions together.

If the data to be stored in a BitVector is small enough (less than the pointer size), it can be stored directly on the BitVector instead of the pointer. This patch makes the data field of the BitVector a union between a pointer and uintptr_t, and uses the latter is the data length is 0.

Previously any object with maps INTERNALIZED_STRING_TYPE or ONE_BYTE_INTERNALIZED_STRING_TYPE would be typed as kInternalizedString. This meant that non-empty constants weren't typed as such. This causes the following issues: - StringConcat couldn't be typed lowered to inline cons string allocation if there were string constants after the first two operands, since these constants would be typed as possibly empty (even if known not to be). - When inlining, a heap constant could end up becoming the input to a ToPrimitiveToString operand. If the ToPrimitiveToString is speculatively lowered to a CheckNonEmpty, then the verifier would fail since the typer can't deal well with intersecting a bitset type (NonEmpty) with a HeapConstantType - the end result type would be (None | HeapConstant..) but the HeapConstantType would retain it's LUB of kInternalizedSeqString, (which includes the EmptyString type) and so the verifier would fail since the output of CheckNonEmpty would still include the EmptyString. To address this, when typing an actual object, check for the empty string and return EmptyString if it is, otherwise type as normal but remove the EmptyString bit since we know it's non-empty.

This is towards closing the perf gap between the MSVC build (which uses link- time optimization) and Clang (where LTO isn't ready on Windows yet). We did a study (see bug) to see which non-inlined functions are hit a lot during render start-up, and which would be inlined during LTO. This should benefit performance in all builds which currently don't use LTO (Android, Linux, Mac) as well as the Win/Clang build. The binary size of chrome_child.dll increases by 2KB with this.

Each frame within an optimized frame needs to be re-verified as being subject to debugging. The specific crash from the linked bug was caused by the fact that non-user JS frames don't necessarily have an associated script. We'd ignore that and attempt to call Script::GetPositionInfo() on the Undefined constant.

In bits.h, instead of relying on C++ overloading for 32/64 bits integers (which can be ambiguous when the input isn't the exact type typedef-ed by uint64_t or uint32_t), use templates and std::enable_if to switch between integers of different sizes. This means that we can get rid of an awkward sizeof check in bit-vector.cc, which was necessary to compile on Mac.
