[patch] Changes for GTRI build

[Jules Bergmann]

I'm getting ready to build a snapshot on the GTRI cluster.  To do this 
cleanly, I need to incorporate the following fixes/feeatures:

  - fixes GNUmakefile.in to install headers in src/vsip/impl/simd

  - adds a '--version=VERSION' option to scripts.  This is useful for
    building snapshots when you can't fit everything in to one day!


While I'm at it, I figured I would include the following optimizations:

  - optimizes matrix copy to use memcpy or an explicit loop when
    possible.

  - optimizes transpose to use SIMD instructions when possible.
