commit 25eeac0cfe7c97ade1be07340e11e7143aab57a6 upstream.
Subsequent patches will rework the logic in armv8_deprecated.c.
In preparation for subsequent changes, this patch moves the emulation
logic earlier in the file, and moves the infrastructure later in the
file. This will make subsequent diffs simpler and easier to read.
This is purely a move. There should be no functional change as a result
of this patch.

commit b4453cc8a7ebbd45436a8cd3ffeaa069ceac146f upstream.
The code for emulating deprecated instructions has two related
structures: struct insn_emulation_ops and struct insn_emulation, where
each struct insn_emulation_ops is associated 1-1 with a struct
insn_emulation.
It would be simpler to combine the two into a single structure, removing
the need for (unconditional) dynamic allocation at boot time, and
simplifying some runtime pointer chasing.
This patch merges the two structures together.
There should be no functional change as a result of this patch.
