      [runtime] Migrate several Date builtins to C++. · 065e9c53
      bmeurer authored 
      Almost all of the Date builtins always call into C++ at least once
anyway, so parsing, compiling and executing the JavaScript wrappers
is just a waste of time.  The most important part here is the Date
constructor itself, which is one of the blockers for new.target in
TurboFan, because compiling the Date constructor takes too much time
with TurboFan (for no reason since we end up in C++ anway).

      [runtime] Replace %to_string_fun with %_ToString. · 7a7b692b
      bmeurer authored 
      Introduce a new macro TO_STRING that maps to %_ToString and use that
instead of calling into any of the ToString/NonStringToString JavaScript
builtins. Also remove the TO_STRING_INLINE macro, which is basically
obsolete with %_ToString. We still have a few uses of ToString left (via
the utils export mechanism), where we need to investigate whether we
will tank badly if we replace them with TO_STRING as well.

      [date] Refactor the %_DateField intrinsic to be optimizable. · e4782a9b
      bmeurer authored 
      Previously the %_DateField intrinsic would also check the object and
throw an exception if you happen to pass something that is not a valid
JSDate, which (a) violates our policy for instrinsics and (b) is hard to
optimize in TurboFan (even Crankshaft has a hard time, but there we will
never inline the relevant builtins, so it doesn't show up). The throwing
part is now a separate intrinsics %_ThrowIfNotADate that throws an
exception in full codegen and deoptimizes in Crankshaft, which means the
code for the current use cases is roughly the same (modulo some register
renamings/gap moves).

      Profiler improvements · feffccca
      jkummerow authored 
      (1) --prof-cpp: Collects ticks like --prof, but ignores code creation events to reduce distortion (so all JS ticks will be "unaccounted"). Useful for profiling C++ code.
(2) --timed-range flag for tick processor: Ignores ticks before the first and after the last call to Date.now(). Useful for focusing on the timed section of a test.
