[PATCH] Revert Thumb-2 conversion of ARM builtins.

[Stephen Hines]

Many of the files in this change use computed jumps and it seems like there
were no tests checked in to verify the new Thumb-2 behavior. The original
change also claims that the "code remains compatible with older CPUs with
no adverse effects". I dispute that there are no adverse effects here,
since the Thumb-2 predicated instructions certainly have different
timings/behavior than their equivalent ARM counterparts.
