Added support for "When an Operand2 constant is used with the instructions MOVS, MVNS, ANDS, ORRS, ORNS, EORS, BICS, TEQ or TST, the carry flag is updated to bit[31] of the constant, if the constant is greater than 255 and can be produced by shifting an 8-bit value" to amber23 |

The mlas_bug testcase tried to use stack without setting stack pointer
register, causing unpredictable behavoiur.
The patch uses an expilict stack area for the test.

Bug fix for bug reported by Botao Lee. The mode bits in the decode stage did not change immediately
after a mode switch from a teqp instruction, but 1 cycle later. This meant the wrong set of registers
was selected for writing to for 1 clock cycle. |

Amber25 improvements:
Use 128-bit wishbone bus, instead of 32-bit to reduce cache miss fetch times
Use a fast barrel shifter for shifts between 0 and 4 to improve timing
Use a 2 cycle full barrel shifter for complex shifts |

Added feature to A25 core to directly use a read value from the write back stage
to reduce the stall to 1 cycle when there is a register conflict with the
following instruction. This increases performance by about 3%. |
