The bit that makes a dcbz instruction a dcbzl instruction was declared as reserved in ppc32 ISAs. However, hardware simply ignores the bit, making code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4. Thus, mark the bit as unreserved so that we properly emulate a simple dcbz in case we're running on non-G5s. While at it, also refactor the code to check the 970 special case during runtime. This way we don't need to differenciate between a 970 dcbz and any other dcbz anymore. We also allow for future improvements to add e500mc dcbz handling.

compute_hflags() will reset DSP h-flags, so MX bit should be initially set for usermode in cpu_state_reset() if DSP ASE is implemented. This change will bring back user-mode support for DSP ASE, since one of the recent changes broke it.

Sign-extend the result of LWR, as is already done for LWL. This is necessary in the case where LWR loads the full word (i.e. the address is actually aligned). In the other cases, it is implementation defined whether the upper 32 bits of the result are unchanged or a copy of bit 31. The latter seems easier to implement. Previously the code used: (oldval & (0xfffffffe << (31 - bitshift))) | (newval >> bitshift) which zeroed the upper bits of the register, losing any previous sign extension in the unaligned cases.

Instead of playing with bit shifting, add two unions (one for 32-bit values, one for 64-bit ones) to access all the DSP elements with the correct type. This make the code easier to read and less error prone, and allow GCC to vectorize the code in some cases.

In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. This leads to names like arm926-arm-cpu but is easiest to handle. No functional changes for -cpu arguments or -cpu ? output.
