Adding constexpr qualifier for helper functions #1050 (#1184)

Browse Source 
* Adding constexpr for exterior product

* Adding constexpr for conjugate

* Adding constexpr for dot, cross and inverse quaternion functions

* Adding constexpr for quat lerp

* Adding constexpr to quaternion comparison functions

lessThan, lessThanEqual, greaterThan, greaterThanEqual

* Adding constexpr for mix functions

mix(scalar, scalar), mix(vec, vec, vec), mix(vec,vec,scalar)

* Adding constexpr for sign(vec) and sign(genFIType)

* Initialize result lessThan, lessThanEqual, greaterThan, greaterThanEqual

Default ctor used in constexpr contex generates warning on gcc

* Adding constexpr to cross(vec, qua) and cross(qua, vec)

* Adding constexpr to glm::translate

* Adding constexpr for exterior product

* Adding constexpr for conjugate

* Adding constexpr for dot, cross and inverse quaternion functions

* Adding constexpr for quat lerp
