dc1a3d3efa Fix Issue 18680 - std.random.LinearCongruentialEngine has opEquals but no toHash 
The custom opEquals is unnecessary. Autogenerated struct equals is correct.

Make rndgen nothrow 
This passes all Phobos tests and would be really nice for no-exceptions situations, instead of appending `assumeWontThrow` to everything. Should be quick.

c99a1855f6 Fix Issue 18327 - std.random.XorshiftEngine is parameterized by UIntType but only works with uint 
Also:
* Add ability to specify shift directions.
* Allow arbitrary XorshiftEngine sizes instead of predefined list only.
* Except when array is small, use index to make speed of `popFront`
  independent of array size.

3a212c0c72 Fix Issue 14001 - Optionally @nogc std.random.randomCover 
Fix Issue 19156 - `@nogc` std.random.randomShuffle

Solution is to use a private `_randomIndex` function that is guaranteed
to be called only with valid bounds.

5d6d784c9a Revert fix for 18631. 
The fix for 18631 broke code. Ranges cannot be marked with const or
inout in generic code. The range API does not require that any functions
be const or inout. In this case, with the changes, choice requires that
length and opSlice be const, breaking any code that uses a range with
choice that does not have a const length or opSlice (which is going to
be a large percentage of ranges with those functions which aren't
arrays).

fa92151982 Fix Issue 17862 - std.random.XorshiftEngine.min is wrong when bits == 32 
XorshiftEngine.min is defined as 0 regardless of template parameters
but an XorshiftEngine cannot produce a value of zero if its internal
state has the same number of bits as the output element type.

db5c1c84b9 Addresses Issue 17832 
Random choice default argument was deciding the type of the
template. I'm not sure if this is a deeper bug, but it can easily be
fixed with this patch which simply overloads the function.
Also added a unittest which would have failed under the old code.
