fmeawad e8dd6981ca Remove V8.External traces due to its high overhead 
The Tracing split CL https://codereview.chromium.org/1707563002 mostly moved the location of
the TRACE call, but it added 2 very high frequency calls related to tracking V8.External.

In most benchmark and devices the added overhead is negligible except on N6 where it gets amplified.
This CL removes those 2 calls until more efficient tracing or a different technique is used.

BUG=588137
LOG=N
