0acbcf9876 Reland "Add out-of-line constant pool support to Arm."
This CL adds out-of-line constant pool support to Arm.  A ConstantPoolBuilder
object is introduced to manage building of the ConstantPoolArray for a given
code object.

This CL depends on the following CLs landing first:

611ea747ef A64: Handle a few TODOs.
Below are notes about some of the TODOs handled.

* In Simulator::Debug:
    We haven't had issues with printing in the debugger for a while. If the
    feature turns out to be still lacking an issue can be raised.

* In SubStringStub::Generate:
    There is no need to jump there. The StringCharAtGenerator is asked to set
    the result in x0, and the return sequence following only uses two instructions.
    Also, we would need to jump after the native counter increment instead of the
    return_x0 label.

* In ArrayPushStub::Generate:
    Raised an internal issue to check and update the ARM code.

* In MacroAssembler::CopyBytes:
    The new code should be faster for bulk copies. Raised an internal issue to
    investigate and improve this function.

* In MacroAssembler::EnterExitFrame:
    Unless we actually find something is wrong, this is working and looks ok.
    Also fixed the comments about the FP registers.

* Comment for BumpSystemStackPointer:
    Removed the comment at the declaration site and updated the TODO in the
    implementation.

- Modifying the ChangeLog file directly when pushing to trunk is now no longer possible. If further modifications to the ChangeLog in manual push-to-trunk mode are required (e.g. after the prepare push LGTM), the change log entry temp file must be edited.

7692811fbf MIPS: Make invalid LHSs a parse-time (reference) error
Port r19976 (73bbd7a)

Original commit message:
This is required by the spec. It also prevents crashes resulting from the attempt to read type feedback for the RHS of an invalid assignment which full codegen never actually allocated info for.

To do: check properly in preparser already.

a868a74cfc Fix branch for resetting change log in push-to-trunk.
The patch is applied to ChangeLog with the "--index" option, which already updates the index of the file. For resetting the ChangeLog to the trunk revision, the trunk branch needs to be stated explicitly in the checkout, otherwise it checks out the already patched HEAD.

3daaba09b6 Pretenure code generation corner case with new space COW arrays.
When advised to pretenure in crankshaft, and the boilerplate is a cow
array, move the elements to old space if it's not already there to avoid
overflowing the store buffer.
