Shuffle movepicker score

Believed to be a speed optimization as benched
on Windows with bench realtime affinity 0x1 deleting
highest and lowest runs:

Base	Test
1549259	1608202
1538115	1583934
1543168	1556938
1536365	1554179
1533026	1582010

Signature remains unchanged and gives anywhere from 1-2% nps
boost in analysis depending on number of cores used.

No functional change.

Speed up picking of killers

Changing the order of the conditions gives
about 1% speed up!

Fix issues detected by Coverity Scan

Most of Coverity Scan reports are false
positives, but in rare cases we have
confirmed (very small) issues.

No functional change.
Speed up by almost 3%

This apparentely silly tweak allows
to speed up the bench by almost 3%.

Not clear why, repeating with perft,
the speed up vanishes.

We can add an integer to a Value

We have defined corresponding operators,
so rely on them to streamline the code
and increase readibility.

Fix Intel compiler warnings

Fallout from previous patch: Intel compiler
is very noisy.

Minor stuff scattered around

Just random minor stuff I found while browsing the code.

Rearrange interpolation formula

Put the division at the end to reduce
rounding errors. This alters the bench
due to different rounding errors, but
should not alter ELO in any way.
