This refines the detection of ld.lld matching the neighbouring clang
file. This is particularly helpful on Ubuntu/Debian when either the
default ld.lld is not installed or the versioned one is preferable for
consistency.

@tqchen I think you last touched the clang equivalent in #3590 .

Thanks to @tqchen for finding this bug.  Emitting ternary operators for
`min` and `max` causes concurrency bugs in CUDA, so we're moving the
ternary op emissions from `CodeGenC` to `CodeGenCHost`.
