mvbits in Fortran Wiki

## Description
Moves `len` bits from positions `frompos` through
`frompos+len-1` of `from` to positions `topos` through
`topos+len-1` of `to`. The portion of argument `to` not
affected by the movement of bits is unchanged. The values of
`frompos+len-1` and `topos+len-1` must be less than
`bit_size(from)`.
## Standard
[[Fortran 95]] and later
## Class
[[Elemental subroutine]]
## Syntax
`call mvbits(from, frompos, len, to, topos)`
## Arguments
 - `from` - The type shall be `integer`.
 - `frompos` - The type shall be `integer`.
 - `len` - The type shall be `integer`.
 - `to` - The type shall be `integer`, of the
same kind as `from`.
 - `topos` - The type shall be `integer`.
