 		800031c94c Improve the Readme 
I tried to improve the Readme because many people in my local
chess club do not understand some of the UCO options properly.
Starting point of this was Cfish's Readme by Ronald de Man,
some internet resources and the Stockfish code itself.

Closes https://github.com/official-stockfish/Stockfish/pull/1898

Initial commit by user @erbsenzaehler, with help from users
Adrian Petrescu, @alayan-stk-2 and Elvin Liu.

No functional change

* Update our continuous integration machinery

Ubuntu 16.04 can now be used with travis. Updating all the other stuff
when there.
Invoking the lld linker seems to save 5 minutes with clang on linux.

No functional change.

Apply -mdynamic-no-pic in a single place in the Makefile instead of 5 places.

No functional change.

erbsenzaehlerandMarco Costalba ca464fc89e Cleanup Makfile for MacOs 
1) Explicitly setting the default lib to the system-default is not
   needed on a Mac. See:
   http://libcxx.llvm.org/docs/UsingLibcxx.html

2) We do no longer need to exclude bmi2-builds from LTO. See:
   https://llvm.org/bugs/show_bug.cgi?id=19416

Changes tested and discussed on FishCooking:

erbsenzaehlerandMarco Costalba 2dd24dc4e6 Use popcount intrinsic with Interl compiler 
It seems that icc used our fallback version of popcount.
Now use intrinsics.

icc version 16.0.2 (gcc version 5.3.0 compatibility)
bmi2 compile
uname -r 4.5.1-1-ARCH

20xbench gives a nice speedup
./stockfish-icc-master 2161515 +- 34462
./stockfish-icc-sse42 2260857 +- 50349

erbsenzaehlerandJoona Kiiski 4048bae47b Use -O3 for all compilers (including ICC) 
There seems to be no benefit from using -fast over -O3 with icc.
So use -O3 everywhere.

No functional change

Resolves #652
