Evan Cheng 9340be4641 For some targets, it's not possible to place GVs in the same memory buffer as the MachineCodeEmitter allocated memory. Code and data has different read / write / execution privilege requirements. 
This is a short term workaround. The current solution is for the JIT memory manager to manage code and data memory separately.

Evan Cheng 19d64ba8bf Correct way to handle CONSTPOOL_ENTRY instructions.

Jim Grosbach ff2b4948ce Support for constant islands in the ARM JIT. 
Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the 
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

Nicolas Geoffray a7557dfe71 Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function 
the stub will resolve.
