Assembler bad code gen for AArch32

[Frank Barchard]

With assembly .S files or inline, the following syntax quietly produces the wrong instruction

VLD1.16       {d2[]-d3[]}, [r3]!

assembles to:

vld1.16 {d2-d3}, [r3]!

The work around is to use , not -

VLD1.16       {d2[],d3[]}, [r3]!

The error is subtle, since the code will build and run and the first value is correct.

clang accepts - and the objdump shows -
It would be better to generate a compile time error, or accept the - syntax.
