Functions from vec3-ext.h and vec4-ext.h can trigger warnings with recent clang

The glm_vec3_isnan, glm_vec3_isinf, glm_vec4_isnan and glm_vec4_isinf sunctions cause compiler warnings with recent clang versions and the -ffast-math compiler flag: "use of NaN is undefined behavior due to the currently enabled floating-point options [-Wnan-infinity-disabled]" or "use of infinity is undefined behavior due to the currently enabled floating-point options [-Wnan-infinity-disabled]"

Changes similar to the following would work around this.

Hi @pm4gh,

Sorry for the delay and thanks for reporting this and providing a solution.

https://github.com/recp/cglm/commit/c12f318fabf14853174419f3892654612186c5c7 should suppress the warnings.
