814e378249 VCMP and VCMPE were the other way around 
- This was due to a misunderstanding of what the E in VCMPE means.
- The E refers to an exception being raised when a QNaN is encountered.
- Added unit tests for VCMP{E}

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.
