Add suport for asl and rol to match existing support for asr and ror

[andrewhop]

Description of changes:

Looking at #2177 I noticed there were some obvious omissions for the ARM constant tweak. This change adds the left version of the right instructions we already have in case a compiler ever decides to use it in the future.

Testing:

Added new test code for the instructions, also updated delocate_test.go to print the first difference after printing the total file:

--- FAIL: TestDelocate (0.01s)
    --- FAIL: TestDelocate/aarch64-Basic (0.00s)
        delocate_test.go:94: delocated output differed.
            Wanted:
            .text
            .file 1 "inserted_by_delocate.c"
....
            Got:
            .text
            .file 1 "inserted_by_delocate.c"
.....
        delocate_test.go:100:
            First difference at line 187:
            Expected:   "    add x22, sp, #(13*32)+96*32"
            Got:        "\tadd x22, sp, #(13*32)+96*32"

Failing for x86-64. 😞 How hard would it be to have separate grammars for x86-64 and ARM?
