KVM: PPC: Book3S: Add MMIO emulation for FP and VSX instructions

This patch provides the MMIO load/store emulation for instructions
of 'double & vector unsigned char & vector signed char & vector
unsigned short & vector signed short & vector unsigned int & vector
signed int & vector double '.

The instructions that this adds emulation for are:

- ldx, ldux, lwax,
- lfs, lfsx, lfsu, lfsux, lfd, lfdx, lfdu, lfdux,
- stfs, stfsx, stfsu, stfsux, stfd, stfdx, stfdu, stfdux, stfiwx,
- lxsdx, lxsspx, lxsiwax, lxsiwzx, lxvd2x, lxvw4x, lxvdsx,
- stxsdx, stxsspx, stxsiwx, stxvd2x, stxvw4x

[paulus@ozlabs.org - some cleanups, fixes and rework, make it
compile for Book E, fix build when PR KVM is built in]

KVM: PPC: BOOK3S: Remove open coded make_dsisr in alignment handler

Use make_dsisr instead of open coding it. This also have
the added benefit of handling alignment interrupt on additional
instructions.

KVM: PPC: E500: exit to user space on "ehpriv 1" instruction

"ehpriv 1" instruction is used for setting software breakpoints
by user space. This patch adds support to exit to user space
with "run->debug" have relevant information.

As this is the first point we are using run->debug, also defined
the run->debug structure.

ppc: Create disassemble.h to extract instruction fields

This is used in a couple places in KVM, but isn't KVM-specific.

However, this patch doesn't modify other in-kernel emulation code:
- xmon uses a direct copy of ppc_opc.c from binutils
- emulate_instruction() doesn't need it because it can use a series
of mask tests.
