The failure was been triggered by turning on --harmony-arrays,
maybe because code size was increased or code was added later
in the bootstrap process. Because it doesn't look like a bug
in anything guarded by --harmony-arrays directly, I'd suggest
shipping the flag and disabling the test on the architectures
where it's been observed to fail. It's already disabled on arm64
and this patch disables it on mips64 as well.

Turning the --harmony-array flag on has been delayed behind
unrelated test failures. Now that those tests are disabled,
land the changes.

This patch fixes WebKit tests based on the new change.

will be ported back to MIPS, and will investigate other code-size
improvements so we can re-enable this test.

This adapts the debugger so that the first break event starting the
stepping process can come from optimized code. TurboFan supports a
debugger statement and hence can be the top-most frame whenever the
