Tim Northover 8189e3d887 ARM: stop emitting blx instructions for most calls on MachO.
I'm really not sure why we were in the first place, it's the linker's job to
convert between BL/BLX as necessary. Even worse, using BLX left Thumb calls
that could be locally resolved completely unencodable since all offsets to BLX
are multiples of 4.

Saleem Abdulrasool 2b42ff6fdb ARM: remove ancient -arm-tail-calls option
This option is from 2010, designed to work around a linker issue on Darwin for
ARM.  According to grosbach this is no longer an issue and this option can
safely be removed.
