[COMMITTED,PATCH 3/3] s390: Rework signbit optab

Currently for a signbit operation instructions tc{f,d,x}b + ipm + srl are emitted. If the source operand is a MEM, then a load precedes the sequence. A faster implementation is by issuing a load either from a REG or MEM into a GPR followed by a shift. In spirit of the signbit function of the C s

My long-term goal is to get all "libsubdir" and similar logic out of the build systems for the runtime libraries themselves, and instead move it to the "meta build system". The idea is the runtime library builds shouldn't just be given the locations they are to install stuff in, and don't need to k
