cc532e449b Tests that the GC doesn't mistake non-pointer constant pool entries as pointers.
Adds a test for ConstantPoolArray to ensure that the GC
doesn't mistake non-pointer entries as pointers and try
to modify them during scavenge operations.

Also adds asserts to ConstantPoolArray::set(int, *Object) to
ensure we don't add new-space pointers in constant pool
array.

97c962c255 Add support for extended constant pool arrays.
This CL adds support for ConstantPoolArrays which contain an extended section.
This will be used to enable larger constant pools than can be addressed by a
single ldr with immediate offset instruction (which has a limit of a 4KB range).
Extended constant pools will have a small section, which is addressable via a
single ldr instruction, and an extended section, which will require a multi-
instruction sequence to load from.

Currently, no code uses the extended ConstantPoolArray's - this change will
be made in a followup CL.

A number of changes are made to the ConstantPoolArray object in order to
support this:
  - Small section layout is now entirely defined by the small layout bitmaps.
  - The ConstantPoolArray no longer extends FixedArrayBase since the length
    field is not useful for extended layouts.
  - Enums are used to represent the type of an entry and the layout section.
  - An iterator can be used to iterate through all elements of a given type.
  - A number of tests were added for these features.

56a486c322 Use full include paths everywhere
- this avoids using relative include paths which are forbidden by the style guide
- makes the code more readable since it's clear which header is meant
- allows for starting to use checkdeps

a199ba80ef Differentate between code target pointers and heap pointers in constant pools.
Separate out code target pointers from normal heap pointer entries in constant
pool arrays so that the GC can correctly relocate these pointers using the
appropriate mechanism.

83c63cf555 Out-of-line constant pool on Arm: Stage 2 - Introduce ConstantPoolArray object.
Second stage of implementing an out-of-line constant pool on Arm.  This CL
Introduces the ConstantPoolArray object which will be used as the backing
store of out-of-line constant pools.  Nothing uses this object yet.
