Cryptic error when parametrizing Bufs with non-native types

[JJ]

The Problem

my $b = Buf[Int].new( 3, -3, 44, -44)

fails with

MVMArray: bindpos expected object register

Ditto for UInt and possibly other non-native Integer types.

Expected Behavior

From these lines:

https://github.com/rakudo/rakudo/blob/master/src/core/Buf.pm6#L18-L20

it looks as it any Int is OK; from the next lines it would seem as if as long as they have use a multiple of 8, is OK. However, the exception is not caught there.

Environment

• Operating system:

• Compiler version (perl6 -v):

  This is Rakudo version 2018.11 built on MoarVM version 2018.11

Same problem occurs with newer versions, though.

Fixed with 7133b81 , adapted tests as well, so can be closed as far as I am concerned.
