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.

hppa: Add support for an emulated TOC/NMI button. Almost all PA-RISC machines have either a button that is labeled with 'TOC' or a BMC/GSP function to trigger a TOC. TOC is a non-maskable interrupt that is sent to the processor. This can be used for diagnostic purposes like obtaining a stack trace/register dump or to enter KDB/KGDB in Linux. This patch adds support for such an emulated TOC button. It wires up the qemu monitor "nmi" command to trigger a TOC. For that it provides the hppa_nmi function which is assigned to the nmi_monitor_handler function pointer. When called it raises the EXCP_TOC hardware interrupt in the hppa_cpu_do_interrupt() function. The interrupt function then calls the architecturally defined TOC function in SeaBIOS-hppa firmware (at fixed address 0xf0000000). According to the PA-RISC PDC specification, the SeaBIOS firmware then writes the CPU registers into PIM (processor internal memmory) for later analysis. In order to write all registers it needs to know the contents of the CPU "shadow registers" and the IASQ- and IAOQ-back values. The IAOQ/IASQ values are provided by qemu in shadow registers when entering the SeaBIOS TOC function. This patch adds a new aritificial opcode "getshadowregs" (0xfffdead2) which restores the original values of the shadow registers. With this opcode SeaBIOS can store those registers as well into PIM before calling an OS-provided TOC handler. To trigger a TOC, switch to the qemu monitor with Ctrl-A C, and type in the command "nmi". After the TOC started the OS-debugger, exit the qemu monitor with Ctrl-A C.
