[interpreter] Add Interpreter{Entry,Exit}Trampoline builtins.

[interpreter] Add Interpreter{Entry,Exit}Trampoline builtins.

Adds interpreter entry and exit trampoline builtins. Also implements the
Return bytecode handler and fixes a few bugs in InterpreterAssembler
highlighted by running on other architectures.

Benedikt / Orion, please take a look. I'll work on Arm64/x86/x64 and add them in
a future patchset.

Paul, Matthew, FYI for Mips and PPC.

LGTM.

[rmcilroy, 2015-07-28 13:00:27]

Modified to pass a seperate BytecodeArray and BytecodeOffset in registers to
avoid having an inner pointer in registers during interpreter dispatch.  

Benedikt, could you take a look please?

[Benedikt Meurer, 2015-07-28 13:06:53]

Looks good to me, thanks for updating this.

DBC: looks like your new use of r5 conflicts with r5 use in CEntryStub. More
details in https://codereview.chromium.org/1253273002/.

Updated with support for other architectures and a couple of fixes exposed by
testing. PTAL.

This shouldn't be an issue because r5 isn't loaded until the end of the
builtitin after the CallRuntime's.

Agreed, this was already my plan :). Rearranged the bullet points to make it
clear which are likely to be explicit bytecodes, and which will be handled in
the entry stub.
