[patch] Fix SIMD loop fusion to handle re-dimensioned expressions

[Jules Bergmann]

This patch uses Adjust_layout_dim so that SIMD loop fusion Ext_data 
access works with re-dimensioned expressions (i.e. those generated by 
Eval_dense_expr).  It also adds a regression test for the case, and 
extends coverage_binary as well.

This was causing the fft test to fail when for the builtin binary packages.

Patch applied.
