Fix small bug in ThumbExpandImm_C; arguments to a call to 'bits' were
...
in the wrong order.

Add emulation for "ADR" operations. Add a ThumbImm8Scaled() convenience function
...
and rename the original ThumbImmScaled() function to ThumbImm7Scaled().

Add two convenience functions: DecodeImmShiftThumb() and DecodeImmShiftARM() to ARMUtils.h.
...
Use them within EmulateInstructionARM.cpp to save repetitive typing.

Add emulation methods for ROR (immediate), ROR (register), and RRX.
...
Turns out that they can be funneled through the helper methods
EmulateShiftImm()/ EmulateShiftReg() as well.
Modify EmulateShiftImm() to handle SRType_ROR and SRType_RRX.
And fix a typo in the impl of utility Shift_C() in ARMUtils.h.

Add emulation methods for LSL (immediate), LSL (register), LSR (immediate), and LSR (register).
...
Create two helper methods EmulateShiftImm() and EmulateShiftReg() and have ASR, LSL, and LSR
delegate to the helper methods which take an extra ARM_ShifterType parameter.
The opcodes tables have not been updated yet to reflect these new entries.

Modify the various shift routines to handle cases where the shift amount comes
...
from the bottom byte of a register.

Add a bunch of utilities and an enum (ARM_ShifterType) for shift and rotate operations pertaining to:
...
o A2.2.1 Pseudocode details of shift and rotate operations
o A8.4.3 Pseudocode details of instruction-specified shifts and rotates

Enhanced the existing ARMExpandImm() and ThumbExpandImm() functions which expand
...
an imm12 into imm32 for ARM or Thumb so that they now handle carry_in/carry_out.
Funnel ARMExpandImm()/ThumbExpandImm() to the enhanced ARMExpandImm_C()/ThumbExpandImm_C()
functions.
