commit a93a3af9 introduces use of PIXMAN_TYPE_RGBA, but it's only available
in pixman >= 0.21.8. If pixman doesn't meet the version requirement, qemu
will fail to build with following message:

Currently the file size requested by user is rounded down to nearest
sector, causing the actual file size could be a bit less than the size
user requested. Since some formats (like qcow2) record virtual disk
size in bytes, this can make the last few bytes cannot be accessed.

This patch fixes it by rounding up file size to nearest sector so that
the actual file size is no less than the requested file size.

The ARM architecture defines that the "IS" variants of TLB
maintenance operations must affect all TLBs in the Inner Shareable
domain, which for us means all CPUs. We were incorrectly implementing
these to only affect the current CPU, which meant that SMP TCG
operation was unstable.

When we implemented ARMv8 in QEMU we retained our legacy loose
wildcarded decoding of the TLB maintenance operations for v7
and earlier CPUs and provided the correct stricter decode for
v8. However the loose decode is in fact wrong for v7MP, because
it doesn't correctly implement the operations which must apply
to every CPU in the Inner Shareable domain.

Move the legacy wildcarding from the not_v8 reginfo array
into the not_v7 array, and move the strictly decoded operations
from the v8 reginfo to v7 or v7mp arrays as appropriate.

Cache and TLB lockdown legacy wildcarding remains in the
not_v8 array for the moment.
