lgtm for the code.
For the tests, I disagree on running the tests with --no-fast-math since
that's
not how V8 is normally run, right?
But I won't block this CL for that.

Are these two sinh tests needed now?
Perhaps you can replace them with the exact fdlibm value of
74.20321057778875.

They do, with --no-fast-math we use the slow library implementation
for exp.
If this is how you normally run these tests, then ok. Otherwise, I think
this is a bad idea since chrome doesn't normally use --no-fast-math,
right?

TWO_M28 and LOG_MAXD have empty lower halves, so the machine code
emitted for
those constants is good enough so that we don't need to load it from a
constant
pool.
Ok.
