*	Minimal implementation of RDHWR to support dummy TLS region.	Pavel Pisa	2019-02-08
\| \| \| \|	Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Implement LL and SC as simple load and store word. SC returns 1 unconditionally.	Pavel Pisa	2019-02-08

*	Added method to retrieve memory location status.	Pavel Pisa	2019-02-07
\| \| \| \| \| \| \|	It can inform if given location is cached or if given range is invalid in address space. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Implement BSHFL instruction and ignore RDHWR instruction.	Pavel Pisa	2019-02-07

*	Remove dependency of ALU operation encoding on MIPS instruction format.	Pavel Pisa	2019-02-07
\| \| \| \|	Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Implemented base for exception handling.	Pavel Pisa	2019-02-06
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Memory stage is chosen to be exception commit stage. Instructions flow postponed and stages holding following instructions are cleaned. Processing of syscall at decode stage as jump to the handler would be better solution in real hardware but for future emulated syscalls it is better to reach consistent state of registers. Memory access caused exceptions would require cleanup even in real hardware. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Reorganize PC handling and implement full REGIMM decode.	Pavel Pisa	2019-02-05
\| \| \| \|	Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Unified instructions table and access type move to machinedefs.h .	Pavel Pisa	2019-02-04
	This allows to specify requirement for RS and RD on instruction basis even for T_R / ALU instructions. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
