534a237015 Move AVX / SSE messages to function PrintVersionInfo (crash fix) 
This information is not needed for normal runs, so it is sufficient
to show it on request (like versions and OpenCL information).

This also fixes a crash caused by undefined order of global constructors:

When the global variable SIMDDetect::detector is initialized before the
global variable debug_file, the first tprintf call in simddetect.cpp
crashes because of a NULL pointer in debug_file. This was only seen when
running with a shared library (libtesseract.so).

19616b07ba lstm: Move class SIMDDetect to new source file and improve code 
Modify also the code to use a singleton. This simplifies the code as
no locking is needed. It also slightly improves the performance because
no check whether the architecture was tested is needed.

b2a0262c59 lstm: Update AVX / SSE support 
* Fix compiler warning (see below)

* Use Linux code for Mingw-w64, too

* Simplify conditional code by using X86_BUILD instead of NONX86_BUILD

* Remove unneeded call of __get_cpuid_max (already called by __get_cpuid)

* Remove unneeded #undef statement

gcc report:

9a4a32137c Fix build for non x86 
cpuid.h is only available for x86 builds. There are lots of non x86
architectures, so simply checking for PowerPC is not enough.
