Hey Yang,
This is the improved HRandom implementation we were talking about offline.
PTAL.
-- Benedikt
Description:
Improve code generation for the HRandom instruction.
Since the per-context random number generator is now
properly seeded upon context creation, we do not need
to check for lazy-initialization anymore, and so we
can implement the HRandom instruction w/o having to
call into the C function (which means we don't need
to MarkAsCall anymore).
TEST=cctest/test-random
