The first try (r238051) to land this was reverted due to ExecutionEngine build failure; that was hopefully addressed by r238788. The second try (r238842) to land this was reverted due to BUILD_SHARED_LIBS failure; that was hopefully addressed by r238953. This patch adds a TargetRecip class for processing many recip codegen possibilities. The class is intended to handle both command-line options to llc as well as options passed in from a front-end such as clang with the -mrecip option. The x86 backend is updated to use the new functionality. Only -mcpu=btver2 with -ffast-math should see a functional change from this patch. All other x86 CPUs continue to *not* use reciprocal estimates by default with -ffast-math. Differential Revision: http://reviews.llvm.org/D8982 llvm-svn: 239001
