Summary:
Returns the size of a list. I have found this to be rather useful in some
development for the AMDGPU backend where we could simplify our .td files
by concatenating list<LLVMType> for complex intrinsics. Doing so requires
us to compute the position argument for LLVMMatchType.
Basically, the usage is in a pattern that looks somewhat like this:
list<LLVMType> argtypes =
!listconcat(base,
[llvm_any_ty, LLVMMatchType<!size(base)>]);
