OK, supposing that the changes to the iWMMXt code in setjmp / longjmp are
deliberate to avoid potential confusion from parts of a source file using
this pattern and other parts not using it. (Given that the document
pointed to implies that NaCl will define ARM_ASSUME_NO_IWMMXT, so the
iWMMXt code won't ever actually be built with the non-null version of this
macro.)
