target-ppc: Altivec 2.07: Change Bit Masks to Support 64-bit Rotates and Shifts
Existing code in the VROTATE, VSL and VSR macros for the Altivec rotate and shift
helpers uses a formula to compute a bit mask used to extract the rotate/shift
amount from the VRB register. What is desired is:
mask = (1 << (3 + log2(sizeof(element)))) - 1
but what is implemented is:
mask = (1 << (3 + (sizeof(element)/2))) - 1
This produces correct answers when "element" is uint8_t, uint16_t or uint_32t. But
it breaks down when element is uint64_t.
This patch corrects the situation. Since the mask is known at compile time, the
macros are changed to simply accept the mask as an argument.
Subsequent patches in this series will add double-word variants of rotates and
shifts and thus take advantage of this fix.

qdev: Keep global allocation counter per bus
When we have 2 separate qdev devices that both create a qbus of the
same type without specifying a bus name or device name, we end up
with two buses of the same name, such as ide.0 on the Mac machines:
dev: macio-ide, id ""
bus: ide.0
type IDE
dev: macio-ide, id ""
bus: ide.0
type IDE
If we now spawn a device that connects to a ide.0 the last created
bus gets the device, with the first created bus inaccessible to the
command line.
After some discussion on IRC we concluded that the best quick fix way
forward for this is to make automated bus-class type based allocation
count a global counter. That's what this patch implements. With this
we instead get
dev: macio-ide, id ""
bus: ide.1
type IDE
dev: macio-ide, id ""
bus: ide.0
type IDE
on the example mentioned above.
This also means that if you did -device ...,bus=ide.0 you got a device
on the first bus (the last created one) before this patch and get that
device on the second one (the first created one) now. Breaks
migration unless you change bus=ide.0 to bus=ide.1 on the destination.
This is intended and makes the bus enumeration work as expected.

elf-loader: add more return codes
The existing load_elf() just returns -1 if it fails to load ELF. However
it could be smarter than this and tell more about the failure such as
wrong endianness or incompatible platform.
This adds additional return codes for wrong architecture, wrong
endianness and if the image is not ELF at all.
This adds a load_elf_strerror() helper to convert return codes into
string messages.
This fixes handling of what load_elf() returns for s390x, other
callers just check the return value for <0 and this remains unchanged.

target-ppc: Add VSX xmax/xmin Instructions
This patch adds the VSX floating point maximum and minimum
instructions:
- xsmaxdp, xvmaxdp, xvmaxsp
- xsmindp, xvmindp, xvminsp
Because of the Power ISA definitions of maximum and minimum
on various boundary cases, the standard softfloat comparison
routines (e.g. float64_lt) do not work as well as one might
think. Therefore specific routines for comparing 64 and 32
bit floating point numbers are implemented in the PowerPC
helper code.
