New code layout - breaking change in cpu_features_macros.h (#194)
This commit helps with platform code separation (fixes #3). It should also help with the build as we can simply include all `impl_*.c` files regardless of OS / arch.

Note: this patch contains breaking changes in `include/cpu_features_macros.h`
 - `CPU_FEATURES_OS_LINUX_OR_ANDROID` does not exist anymore
 - `CPU_FEATURES_OS_FREEBSD`, `CPU_FEATURES_OS_ANDROID` and `CPU_FEATURES_OS_LINUX` are now mutually exclusive (i.e. `CPU_FEATURES_OS_ANDROID` does not imply `CPU_FEATURES_OS_LINUX`)
 - `CPU_FEATURES_OS_DARWIN` has been renamed into `CPU_FEATURES_OS_MACOS` to be able to target non-Mac Apple products (IOS, TV, WATCH). They are now targetable with `CPU_FEATURES_OS_IPHONE`. This matches Apple naming convention described in [this stackoverflow](https://stackoverflow.com/a/49560690).

Fix SSE detection on non-AVX CPUs (#135)
Fixes #4. This is based on #115 with a few modifications:
 - Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
 - Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
 - Added tests for Atom, Nehalem, and P3 processors,

Thx to @gadoofou87 for providing the original PR.
It also removes the need for #92

* Fix SSE detection on non-AVX CPUs
* Fixes typo
* Mock OSX sysctlbyname in tests
* Also update other tests
* FakeCpu is reset between each tests
* Fix conflicting name on Windows
* Disable pre AVX cpu sse detection tests on Windows
* Guard OS specific code with macros
* Fix missing import for tests
* Fix wrong function prototype
* Fix wrong mocking of P3 on Windows
* Completely guard OS specific parts in x86 tests
* Store DWORD instead unsigned long for x86 tests
