target-hppa: Add framework and enable compilation This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.

target/hppa: Allow, but diagnose, LDCW aligned only mod 4 The PA-RISC 1.1 specification says that LDCW must be aligned mod 16 or the operation is undefined. However, real hardware only generates an unaligned access trap for unaligned mod 4. Match real hardware, but diagnose with GUEST_ERROR a violation of the specification. At the same time fix a bug in the initialization of mop, where the size was specified twice, and another to free the zero temporary.

DEF_HELPER_1(diag_btlb, void, env)
target/hppa: Add "diag 0x101" for console output support For debugging purposes at the early stage of the bootup process, the SeaBIOS-hppa firmware sometimes needs to output characters to the serial console. Note that the serial console is the default output method for parisc machines. At this stage PCI busses and other devices haven't been initialized yet. So, SeaBIOS-hppa will not be able to find the correct I/O ports for the serial ports yet. Instead, add an emulation for the "diag 0x101" opcode to assist here. Without any other dependencies, SeaBIOS-hppa can then load the character to be printed in register %r26 and issue the diag assembly instruction. The qemu diag_console_output() helper function will then print that character to the first serial port.
