Description
The prior BE porting project 'skipped' some formats. These simply have the SIMD disabled when building under a BE SIMD machine. This bug is to re-enable the SIMD logic so it works in these formats. NOTE, some of these are NOT trivial when it comes to SIMD usage, lol. Dynamic format is handled all in a separate bug #2892, but is 100% related to this one. But that beast is very ugly, and should be done with its own PR, since there will likely be hundreds of porting points in the code.

Research direction
The remaining unchecked formats are SunMD5 and 7z, including utf8 for 7z; begin by reviewing their existing big-endian SIMD handling and the prior BE porting work. Done means the SIMD logic is re-enabled and works when building these formats on a big-endian SIMD machine, while dynamic format remains in issue #2892.
