    pub unsafe fn _bextr2_u32(a: u32, control: u32) -> u32

This is supported on x86-64 and target feature `bmi1` only.

Extracts bits of `a` specified by `control` into the least significant bits of the result.

Bits `[7,0]` of `control` specify the index to the first bit in the range to be extracted, and bits `[15,8]` specify the length of the range.
