PPC32: Fix stack collision between FP and CR save areas.

The changes to CR spill handling missed a case for 32-bit PowerPC.
The code in PPCFrameLowering::processFunctionBeforeFrameFinalized()
checks whether CR spill has occurred using a flag in the function
info.  This flag is only set by storeRegToStackSlot and
loadRegFromStackSlot.  spillCalleeSavedRegisters does not call
storeRegToStackSlot, but instead produces MI directly.  Thus we don't
see the CR is spilled when assigning frame offsets, and the CR spill
ends up colliding with some other location (generally the FP slot).

This patch sets the flag in spillCalleeSavedRegisters for PPC32 so
that the CR spill is properly detected and gets its own slot in the
stack frame.

Fix ARM FastISel tests, as a first step to enabling ARM FastISel

ARM FastISel is currently only enabled for iOS non-Thumb1, and I'm working on
enabling it for other targets. As a first step I've fixed some of the tests.
Changes to ARM FastISel tests:
- Different triples don't generate the same relocations (especially
  movw/movt versus constant pool loads). Use a regex to allow either.
- Mangling is different. Use a regex to allow either.
- The reserved registers are sometimes different, so registers get
  allocated in a different order. Capture the names only where this
  occurs.
- Add -verify-machineinstrs to some tests where it works. It doesn't
  work everywhere it should yet.
- Add -fast-isel-abort to many tests that didn't have it before.
- Split out the VarArg test from fast-isel-call.ll into its own
  test. This simplifies test setup because of --check-prefix.

Add bitcast to store of personality function.

The personality function is user defined and may have an arbitrary result type.
The code assumes always i8*. This results in an assertion failure if a different
type is used. A bitcast to i8* is added to prevent this failure.

SectionMemoryManager shouldn't be a JITMemoryManager. Previously, the 
EngineBuilder interface required a JITMemoryManager even if it was being used 
to construct an MCJIT. But the MCJIT actually wants a RTDyldMemoryManager. 
Consequently, the SectionMemoryManager, which is meant for MCJIT, derived 
from the JITMemoryManager and then stubbed out a bunch of JITMemoryManager 
methods that weren't relevant to the MCJIT.

This patch fixes the situation: it teaches the EngineBuilder that 
RTDyldMemoryManager is a supertype of JITMemoryManager, and that it's 
appropriate to pass a RTDyldMemoryManager instead of a JITMemoryManager if 
we're using the MCJIT. This allows us to remove the stub methods from 
SectionMemoryManager, and make SectionMemoryManager a direct subtype of 
RTDyldMemoryManager.
