We have eliminated all normal uses of hflags_nmsr. We need
not even compute it except when we want to migrate. Rename
the field to emphasize this.
Remove the fixme comment for migrating access_type. This value
is only ever used with the current executing instruction, and
is never live when the cpu is halted for migration.

Keep all hflags computation in one place, as this will be
especially important later.
Introduce a new POWERPC_FLAG_HID0_LE bit to indicate when
LE should be taken from HID0. This appears to be set if
and only if POWERPC_FLAG_RTC_CLK is set, but we're not
short of bits and having both names will avoid confusion.
Note that this was the only user of hflags_nmsr, so we can
perform a straight assignment rather than mask and set.

Move the functions to a new file, helper_regs.c.
Note int_helper.c was relying on helper_regs.h to
indirectly include qemu/log.h.
