target-xtensa: add special and user registers

Special Registers hold the majority of the state added to the processor
by the options. See ISA, 5.3 for details.

User Registers hold state added in support of designer's TIE and in some
cases of options that Tensilica provides. See ISA, 5.4 for details....

target-xtensa: implement disas_xtensa_insn

Set up disas_xtensa_insn switch structure, mark required options on high
level groups. Implement arithmetic/bit logic/jump/call0.

Implement code generation loop with single step/breakpoint checking.

target-xtensa: add sample board

Sample board and sample CPU core are used for debug and may be used for
development of custom SoC emulators.

This board has two fixed size memory regions for DTCM and ITCM and
variable length SRAM region.
