4981d5ab89 Convert everything to new inline scheme (#57) (#72)
* Convert everything to new inline scheme

* Add both extern and inline for some SSE vs. non-SSE functions

Some functions had nice, compact SSE implementations but bulky non-SSE
implementations, so this commit inlines just the implementations that make
sense. Also updated documentation.

* Convert HINLINE and HEXTERN to HMM_INLINE and HMM_EXTERN

* Fix compile process so the SSE option is consistently defined

* Fix link error

* Documentation

* Added function prototype for operator ==

* Added != operator for hmm_vec2, hmm_vec3, hmm_vec4

* Add C versions of equality checks

Also made the C++ tests actually run...😳

98f535aeec Handle zero-vector normalization. (#63)
* Handle zero-vector normalization.

When normalizing a vectors, we have to check whether vector length is
not zero, to avoid dividing by zero when normalizing zero-vectors.

* Test for normalization of zero vectors

ff4513ff33 Make it usable on non-SSE platforms (#60)
* at one place HANDMADE_NO_SSE instead of HANDMADE_MATH_NO_SSE was used
* introduce HANDMADE_MATH__USE_SSE for the SSE #ifdefs throughout code
  - use #ifdef HANDMADE_MATH_NO_SSE at only one place
* only use SSE (#define HANDMADE_MATH__USE_SSE) if the targetplatform
  actually supports it
  => users don't have to #define HANDMADE_MATH_NO_SSE on ARM etc
* at one place HMM_SqrtF instead of HMM_SquareRootF was used
