[patch] SIMD load_unaligned, scalar load optimization

[Jules Bergmann]

This patch contains two unrelated SIMD items:

- Implements a SIMD load_unaligned function for unaligned loads, and 
adds unit test.

- Optimizes SIMD loop fusion handling of scalar values to load the value 
into a SIMD register once, rather than each time it is accessed.

On a PPC 970FX, this improves floating-point scalar * vector performance 
at 2048 points from 241 MFLOP/s  to 1942 MFLOP/s.

Patch applied.
