Lower Fortran intrinsic to a runtime call/llvm intrinsic
This patch brings in code which can lower a Fortran intrinsic to
a runtime call or an llvm intrinsic. For math intrinsics the
runtime call is to the `math` or `pgmath` library. Non-math
intrinsics are covered by the Flang runtime. A distance computation
mechanism is introduced to find the runtime function that closely
matches the types of the intrinsic call.
In this patch, the `abs` intrinsic is lowered in the following way,
-> Integer version is lowered as a group of MLIR/FIR operations
-> Real version is lowered to llvm intrinsics
-> Complex version is lowered to the `math_hypot` runtime function
This patch is part of upstreaming from the fir-dev branch of https://github.com/flang-compiler/f18-llvm-project
