Update test262 expectations for 64-bit precision double for ARM and MIPS.

Update test262 expectations for 64-bit precision double for ARM and MIPS.

The two tests (S8.5_A2.1, S8.5_A2.2) fail on ia32 Linux and simulators.
They do pass on ARM and MIPS hardware under Linux, and on the other
supported platforms and architectures.

They are now marked PASS || FAIL_OK. 

BUG=
TEST=test262/S8.5_A2.1, test262/S8.5_A2.2

I think we should just set the expectations for these two tests to "PASS ||
FAIL_OK" for all architectures. I don't see the point in micro-managing the
expectations to exactly describe the situation anymore (especially with regard
to simulators). We already do the same for e.g. S15.8.2.16_A7 which has a
related cause.

LGTM. Landed.
