llvm-targets: drop soft-float · 60b06456

Summary:
The llvm-targets file records `mattr` values, and
while interrogating `clang` for the target, we might
stumble upon `+soft-float-abi`, however ghc does not support
full soft-float, and as such passing `+soft-float` to `llc`
will result in segfaults for any function passing float
registers F1, ... in the ARM Instruction Selection Pass.
