0b351a64db It is not safe to execute split condition's true branch first all the time. If split 
condition predicate is GT or GE then execute false branch first.

30440c6c4e Fix this testcase: there are two matches for 
llvm.cttz.i64 because of the declaration of
the intrinsic.  Also, emit-llvm is automatic
and doesn't need to be specified.

"True Loop" and "False Loop" naming terminology to refer two loops
after loop cloning is confusing. Instead just use A_Loop and B_Loop.

5da3149de5 When Intrinsic::getName is constructing names for overloaded intrinsics, 
use the ValueType name instead of the llvm type name, to match what the
verifier expects. For integers these are the same, but for floating-point
values the intrinsics use f32/f64 instead of float/double.
