template<class Flags> void copy_from( const bool* mem, Flags flags );		(parallelism TS v2)

The load function replaces all elements of a simd_mask such that the i-th element is assigned with mem[i] for all i in the range of [​0​, size()).

Parameters

mem	-	a pointer into an array where [mem, mem + size()) is a valid range
flags	-	if of type vector_aligned_tag, the load constructor may assume mem to point to storage aligned by memory_alignment_v<simd_mask>
Type requirements
- is_simd_flag_type_v<Flags> must be true.
