- OpMemberDecorate introduces a single decoration for a <id,

- OpDecorationGroup introduces a new value category which has no
  representation downstream at all. This is safely implemented by
  doing nothing at all [we don't need to be able to introspect later].

- OpGroupDecorate applies all decorations in a decoration group to each

A lot of arrays in VertexProgram and PixelProgram have fixed sizes,
so programs that have more nested loops or ifs or deeper call stacks
can cause OOB accesses, which causes security issues in Chromium.

Index clamping was added to prevent any OOB memory accesses here.

This could eventually be fixed properly by first verifying these sizes
and giving shader compile errors when these limits are exceeded.
