Be more precise about which conversions of NaNs are Inexact. (These are not Inexact as defined by IEEE754, but that seems like a reasonable way to abstract what happens: information is lost.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57218 91177308-0d34-0410-b5e6-96231b3b80d8 2008-10-06 22:59:10 +00:00			`; ModuleID = 'nan.bc'`
