09aa3f0ef3 The BLX instruction is encoded differently than the BL, because why not? In 
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.

Attempt to get the encoding at slightly more correct with this.

377296e301 Assign arguments of Neon intrinsic macros to local temporaries. 
Since we're casting them for the calls to the builtins, we need this to
