Wip signed integer overflow cppcheck

Fix for cppcheck signed integer overflow errors

See merge request !21

The type of expression '1<<31' is signed int and this causes cppcheck to
issue the following warning.

src/gf_w32.c:681]: (error) Signed integer overflow for expression
'1<<31'.

gf_cpu.c: fix pclmul detection and add portable cpuid feature bit defs

See merge request !20

Correct invalid check for pclmul support. Was checking SSE3 (1 << 0) vs. PCLMUL (1 << 1).

Gf32 mul silence warning

silence warning like

```
/slow/kchai/ceph/src/erasure-code/jerasure/gf-complete/src/gf_w32.c: In function ‘gf_w32_cfmgk_multiply_region_from_single’:
/slow/kchai/ceph/src/erasure-code/jerasure/gf-complete/src/gf_w32.c:410:5: warning: ‘a’ may be used uninitialized in this function [-Wmaybe-uninitialized]
   g = _mm_insert_epi64 (a, g_star, 0);
     ^
```

See merge request !19

in gf_w32_cfmgk_multiply_region_from_single(), follow warning is
reported by gcc:

gf-complete/src/gf_w32.c:410:5: warning: ‘a’ may be used uninitialized
in this function [-Wmaybe-uninitialized]
   g = _mm_insert_epi64 (a, g_star, 0);
     ^

actually, we are using `a` as a dummy parameter for initializing `g` and
`q`. and only the lower lower 64 bits of them are used when doing
calculation. but their lower 64 bits are always initialized using
_mm_insert_epi64(). so this is a false alarm.

but we can silence this warning by moving the statement initializing `a`
up before passing it to  _mm_insert_epi64(). this change does not hurt
the performance.
