Bill Schmidt daa65f5e08 This patch makes medium code model the default for 64-bit PowerPC ELF.
When the CodeGenInfo is to be created for the PPC64 target machine,
a default code-model selection is converted to CodeModel::Medium
provided we are not targeting the Darwin OS.  Defaults for Darwin
are unaffected.
