target-sparc: add ST_BLKINIT_ ASIs for UA2005+ CPUs
In OpenSPARC T1+ TWINX ASIs in store instructions are aliased
with Block Initializing Store ASIs.

"UltraSPARC T1 Supplement Draft D2.1, 14 May 2007" describes them
in the chapter "5.9 Block Initializing Store ASIs"

Integer stores of all sizes are allowed with these ASIs.

target-sparc: store the UA2005 entries in sun4u format
According to chapter 13.3 of the
UltraSPARC T1 Supplement to the UltraSPARC Architecture 2005,
only the sun4u format is available for data-access loads.

Store UA2005 entries in the sun4u format to simplify processing.

Alex Bennée d10eb08f5d cputlb: drop flush_global flag from tlb_flush
We have never has the concept of global TLB entries which would avoid
the flush so we never actually use this flag. Drop it and make clear
that tlb_flush is the sledge-hammer it has always been.

Alex Bennée 1f5c00cfdb qom/cpu: move tlb_flush to cpu_common_reset
It is a common thing amongst the various cpu reset functions want to
flush the SoftMMU's TLB entries. This is done either by calling
tlb_flush directly or by way of a general memset of the CPU
structure (sometimes both).

This moves the tlb_flush call to the common reset function and
additionally ensures it is only done for the CONFIG_SOFTMMU case and
when tcg is enabled.

In some target cases we add an empty end_of_reset_fields structure to the
target vCPU structure so have a clear end point for any memset which
is resetting value in the structure before CPU_COMMON (where the TLB
structures are).

While this is a nice clean-up in general it is also a precursor for
changes coming to cputlb for MTTCG where the clearing of entries
can't be done arbitrarily across vCPUs. Currently the cpu_reset
function is usually called from the context of another vCPU as the
architectural power up sequence is run. By using the cputlb API
functions we can ensure the right behaviour in the future.
