IB/core: Add mitigation for Spectre V1
[ Upstream commit 61f259821dd3306e49b7d42a3f90fb5a4ff3351b ]
Some processors may mispredict an array bounds check and
speculatively access memory that they should not. With
a user supplied array index we like to play things safe
by masking the value with the array size before it is
used as an index.
