b26e98f19b VectorICs: ia32 store ics need a virtual register.
Some pretty hacky code was used to carry out the tail-call
handler dispatch on ia32 vector stores due to a lack
of free registers. It really tanks performance. A better
approach is to use a virtual register on the isolate.

00a07bc1b7 Remove inline header includes from non-inline headers (1).
This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 7 violations of that rule in the
code. However there now is the "tools/check-inline-includes.sh" tool
detecting such violations.

58109a2c50 Remove several grab-bag includes from the v8.h header.
This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.

Also the number of includes inside the v8.h file has been drastically
reduced. Basically the last missing piece is the inclusion of the big
objects-inl.h file.

This in turn makes many headers follow the IWYU principle.

bc8041dc2b Unify "runtime-style" IC functions with Runtime intrinsics
Previous to this CL, ICs used a slightly different code idiom
to get to C++ code from generated code than runtime intrinsics,
using an IC_Utility class that in essence provided exactly
the same functionality as Runtime::FunctionForId, but in its
own quirky way.

This CL unifies the two mechanisms, folding IC_Utility
away by making all IC entry points in C++ code, e.g. IC
miss handlers, full-fledged runtime intrinsics. This makes
it possible to eliminate a bunch of ad-hoc declarations and
adapters that the IC system had to needlessly re-invent.

As a bonus and the original reason for this yak-shave:
IC-related C++ runtime functions are now callable from
TurboFan.

8965b683ce Debugger: use debug break slot to break on call.
Break point at calls are currently set via IC. To change this, we
need to set debug break slots instead. We also need to distinguish
those debug break slots as calls to support step-in.

To implement this, we add a data field to debug break reloc info to
indicate non-call debug breaks or in case of call debug breaks, the
number of arguments. We can later use this to find the callee on the
evaluation stack in Debug::PrepareStep.

eac7f04669 Add support for Embedded Constant Pools for PPC and Arm
Embed constant pools within their corresponding Code
objects.

This removes support for out-of-line constant pools in favor
of the new approach -- the main advantage being that it
eliminates the need to allocate and manage separate constant
pool array objects.

Currently supported on PPC and ARM.  Enabled by default on
PPC only.

This yields a 6% improvment in Octane on PPC64.

368a503cc1 Revert of Externalize deoptimization reasons. (patchset #7 id:120001 of https://codereview.chromium.org/874323003/)
Reason for revert:
This CL breaks RelocInfo::INTERNAL_REFERENCE (and maybe others that come after DEOPT_REASON), which is currently (mostly) unused on tip-of-tree, but will be used for jump tables soon(ish) and should therefore work. It seems to be a problem with implicitly assumptions about the number of reloc info modes. Needs further investigation.

ec42e002da Externalize deoptimization reasons.
1) The hardcoded strings were converted into DeoptReason enum.

2) Deopt comment were converted into a pair location and deopt reason entries so
the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.

3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.

a17289f4bc [turbofan] Drop broken StaticParameterTraits.
The StaticParameterTraits are broken by design, and cause way too much
trouble. The compilers usually pick the wrong specialization (i.e. the
default specialization is picked for Load and Phi even tho there is a
specialization for MachineType), which is not only the reason why GVN is
ineffective and slow, but can also lead to correctness issues in some
rare cases.

Also clean up some minor bugs/inconsistencies on the way.
