tools/memory-model: Keep assembly-language litmus tests

This commit retains the assembly-language litmus tests generated from
the C-language litmus tests, appending the hardware tag to the original
C-language litmus test's filename. Thus, S+poonceonces.litmus.AArch64
contains the Armv8 assembly language corresponding to the C-language
S+poonceonces.litmus test.

This commit also updates the .gitignore to avoid committing these
automatically generated assembly-language litmus tests.

tools/memory-model: Move from .AArch64.litmus.out to .litmus.AArch.out

When the github scripts see ".litmus.out", they assume that there must be
a corresponding C-language ".litmus" file. Won't they be disappointed
when they instead see nothing, or, worse yet, the corresponding
assembly-language litmus test? This commit therefore swaps the hardware
tag with the "litmus" to avoid this sort of disappointment.

This commit also adjusts the .gitignore file so as to avoid adding these
new ".out" files to git.

tools/memory-model: Add scripts to test memory model

This commit adds a pair of scripts that run the memory model on litmus
tests, checking that the verification result of each litmus test matches
the result flagged in the litmus test itself. These scripts permit easier
checking of changes to the memory model against preconceived notions.

To run the scripts, go to the tools/memory-model directory and type
"scripts/checkalllitmus.sh". If all is well, the last line printed will
be "All litmus tests verified as was expected."
