6a5d81b172 tcg: ppc64: Fix mask generation for vextractdm 
In function do_extractm() the mask is calculated as
dup_const(1 << (element_width - 1)). '1' being signed int
works fine for MO_8,16,32. For MO_64, on PPC64 host
this ends up becoming 0 on compilation. The vextractdm
uses MO_64, and it ends up having mask as 0.

Explicitly use 1ULL instead of signed int 1 like its
used everywhere else.

I wasn't expecting such a performance lost in both VPRTYBD and VPRTYBQ,
I'm not sure if it's worth to move those instructions. Comparing the
assembly of the helper with the TCGop they are pretty similar, so
I'm not sure why vprtybd took so much more time.

611bc69bf6 target/ppc: Move V(ADD|SUB)CUW to decodetree and use gvec 
This patch moves VADDCUW and VSUBCUW to decodtree with gvec using an
implementation based on the helper, with the main difference being
changing the -1 (aka all bits set to 1) result returned by cmp when
true to +1. It also implemented a .fni4 version of those instructions
and dropped the helper.

dc46167a22 target/ppc: Moved VMLADDUHM to decodetree and use gvec 
This patch moves VMLADDUHM to decodetree a creates a gvec implementation
using mul_vec and add_vec.

rept    loop    master             patch
8       12500   0,01810500         0,00903100 (-50.1%)

8000    12      0,15326700         0,21725200 (+41.7%)

The significant difference in performance when REPT is low and LOOP is
high I think is due to the fact that the new implementation has a higher
translation time, as when using a helper only 5 TCGop are used but with
the patch a total of 10 TCGop are needed (Power lacks a direct mul_vec
equivalent so this instruction is implemented with the help of 5 others,
vmuleu, vmulou, vmrgh, vmrgl and vpkum).

e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN 
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.

This can help to make some code independent from qemu too.

gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.
