54d051977f emit_x64: Use movdqa instead of movaps in EmitPackedSubU8 
While movaps and movdqa are behaviourly equivalent, using movaps may incur
a domain crossing penalty on some microarchitectures. This is because
movaps is an instruction in the floating-point domain while the following
instructions are in the integer domain.

52fdec5892 CMakeLists: Add support for LLVM on Windows 
The LLVM project provides a clang-based MSVC compatible toolset for
Microsoft Visual Studio. This suite is sometimes refered to as "clang-cl".

This patch adds a few compiler flags to support this toolset.

3621a925b2 reg_alloc: Register allocator related constraints belong with the rest of the register allocator 
HostLocToReg64 contained two DEBUG_ASSERTs invloving constraints that
really belonged to the register allocator.

The register allocator prevents allocation of RSP and R15 because those
are reserved for the stack pointer and the state pointer respectively.

14eb70d7e4 VFP: Fixed the VCVT behavior when converting from unsigned 32-bit values. (#51) 
Use a 64-bit register to hold the values so that we don't end up interpreting them as signed values.

d589c63107 Implemented the ARM SEL instruction, with tests. (#39) 
The test for this instruction is very peculiar. As the instruction's behavior depends on the value of the CPSR, we generate a MSR instruction after each SEL instruction to change the CPSR.
