The CL https://codereview.chromium.org/1409013004 added / changed some test cases.
Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result
check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined
functions has different behavior comparing with GCC ia32 build and x87 build. The major
difference is sse float register still has single precision rounding semantic. While X87
register has no such rounding precsion semantic when directly use register value. The V8
turbofan JITTed has exactly same result in both X87 and IA32 port.
So we add the following sentence to do type case to keep the same precision.
float expect = *i * *j; // *i + *j, etc.
For test case "RunFloat64MulAndFloat64Add1 / RunFloat64MulAndFloat64Add2 / RunFloat64MulAndFloat64Sub1
/ RunFloat64MulAndFloat64Sub2", the expected result calcaulated by GCC has difference precsion
when comparing with V8 turbofan result for X87 platform. (Turbofan X87 result is the same as
IA32 GCC and IA32 Turbofan). So we have to disable those four cases for X87 port.

The callees are expected to properly set the number of actual
arguments passed to the callee, which is now represented correctly
in the TurboFan graphs by a new Parameter right before the context
Parameter. Currently this is only being used for outgoing calls.
Note that this requires disabling two of the TF code stub tests,
because of the JavaScript graphs are not automagically compatible
with abitrary (incoming) code stub interface descriptors. If we
want to support JS code stubs at all, then we need to find a sane
way to feed in this information.
Drive-by-fix: Don't insert a direct call to a classConstructor.

This stages the general purpose inlining mechanism in TurboFan and also
disables the remaining tests that still fail. We do this to get test
coverage early and to avoid regressing inlining as we go along.

Swarming won't support an incremental data file. By just
sorting the lowest hanging fruits to the beginning we
already get a big bang for the buck (>80% of the improvement
we get otherwise).
This will require semi-regular manual updates of the
slowest tests.

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.

After https://codereview.chromium.org/1180433003 the code-size exceeeds
the limit for MIPS. We have some optimizations in place for MIPS64 that
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
