Jinke Fan abd1dd6617 Add Hygon Dhyana processor support 
Background:
    Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture
    between AMD and Haiguang Information Technology Co.,Ltd., aims at
    providing high performance x86 processor for China server market.
    Its first generation processor codename is Dhyana, which
    originates from AMD technology and shares most of the
    architecture with AMD's family 17h, but with different CPU Vendor
    ID("HygonGenuine")/Family series number(Family 18h).

Related Hygon kernel patch can be found on:
http://lkml.kernel.org/r/5ce86123a7b9dad925ac583d88d2f921040e859b.1538583282.git.puwen@hygon.cn

Best regards.

Sam Lantinga 8728ce4448 Fixed bug 4557 - SDL_SIMDAlloc and *Free should be in the public interface 
Martin Gerhardy

These functions are really useful and should get exposed imo.

Sylvain Becker 09b462044f Windows: NEON detection and intrinsic includes on Visual Studio 
Visual Studio doesn't define __ARM_ARCH nor _ARM_NEON, but _M_ARM and _M_ARM64,
so SDL_HasNEON() was bypassed.

PF_ARM_NEON_INSTRUCTIONS_AVAILABLE doesn't see to be defined (but still works
 when defined as 19).

Ryan C. Gordon 4df859c586 cpuinfo: Added SDL_HasAVX512F(). 
This checks for the "foundation" AVX-512 instructions (that all AVX-512
compatible CPUs support).

Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later. 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
