target-tricore: Add instructions of RR opcode format, that have 0x4b as the first opcode
Add instructions of RR opcode format, that have 0x4b as the first opcode.
Add helper functions:
* parity: Calculates the parity bits for every byte of a 32 int.
* bmerge/bsplit: Merges two regs into one bitwise/Splits one reg into two bitwise.
* unpack: unpack a IEEE 754 single precision floating point number as exponent and mantissa.
* dvinit_b_13/131: (ISA v1.3/v1.31)Prepare operands for a divide operation,
where the quotient result is guaranteed to fit into 8 bit.
* dvinit_h_13/131: (ISA v1.3/v1.31)Prepare operands for a divide operation,
where the quotient result is guaranteed to fit into 16 bit.
OPCM_32_RR_FLOAT -> OPCM_32_RR_DIVIDE.
