 While trying to debug #11994 we discovered that "info all-registers" in
 gdb does not show the d* series of registers, suggesting that gdb and/or
 the kernel were not compiled to support debugging ARM's NEON extensions.

 According to gdb's disassembly, the code being analyzed was using the d
 registers, but we could not see their values.

 has a recipe on how to enable NEON debugging support.

 At this time we do not know if this is critical to solving #11994 or not.
