[X86] Introduce WriteFLDC for x87 constant loads.
Summary: {FLDL2E, FLDL2T, FLDLG2, FLDLN2, FLDPI} were using WriteMicrocoded. - I've measured the values for Broadwell, Haswell, SandyBridge, Skylake. - For ZnVer1 and Atom, values were transferred form InstRWs. - For SLM and BtVer2, I've guessed some values :( Reviewers: RKSimon, craig.topper, andreadb Subscribers: gbedwell, llvm-commits Differential Revision: https://reviews.llvm.org/D47585 llvm-svn: 333656
