From: Luis Pires <luis.pires@eldorado.org.br>
New macros that add FLAGS and FLAGS2 checking were added for
both TRANS and TRANS64.
Signed-off-by: Luis Pires <luis.pires@eldorado.org.br>
[ferst: - TRANS_FLAGS2 instead of TRANS_FLAGS_E
- Use the new macros in load/store vector insns ]

Moved the instructions vmulesb, vmulosb, vmuleub, vmuloub,
vmulesh, vmulosh, vmuleuh, vmulouh, vmulesw, vmulosw,
muleuw and vmulouw from legacy to decodetree. Implemented
the instructions vmulesd, vmulosd, vmuleud, vmuloud.

xsmaddqp[o]: VSX Scalar Multiply-Add Quad-Precision [using round to Odd]
xsmsubqp[o]: VSX Scalar Multiply-Subtract Quad-Precision [using round
to Odd]
xsnmaddqp[o]: VSX Scalar Negative Multiply-Add Quad-Precision [using
round to Odd]
xsnmsubqp[o]: VSX Scalar Negative Multiply-Subtract Quad-Precision
[using round to Odd]

xvcvspbf16 implementation is incorrectly setting both XX and FI bits in
FPSCR, while the hardware sets only XX bit (as stated in the ISA). This
happens because do_float_check_status calls float_inexact_excp, which
sets both bits (as should happen in instructions like fsub, but not
conversion instructions like xvcvspbf16 and xvcvdpsp, which also has
this problem).
Example:
qemu: xvcvspbf16(0x40490fdb) results fpscr=0x82020000 (FI==1)
hardware: xvcvspbf16(0x40490fdb) results fpscr=0x82000000 (FI==0)

I believe Victor would want to standardize whether he would like his name
using acute or not (Víctor vs Victor). Both are fine, but sticking with
a single one will make git happier because, as we can see here, git thinks
that Víctor and Victor are 2 different people.
For reference, Victor has 2 patches upstream without using acute.
Thanks,
Daniel

I haven't seen any regressions with this series and it should be included
in the next ppc PR.
