Chris,

When asm-verbose=true, it is spending the extra time here:

 %   cumulative   self                self    total
time   seconds   seconds     calls    s/call  s/call  name
33.67     17.19    17.19       849    0.02     0.04  AddModuleTypesToPrinter
17.51     26.13     8.94 265849169    0.00     0.00  llvm::Value::getType()
 8.74     30.59     4.46 258948922    0.00     0.00
 ::TypeFinder::IncorporateType
 3.25     32.25     1.66   5242575    0.00     0.00
 ::TypeFinder::IncorporateValue
