Kazu Hirata b6a01caa64 [llvm/unittests] Use std::nullopt instead of None (NFC) 
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

Matt Arsenault 58f843a5b3 GlobalISel: Prepare to allow other target unit tests 
Currently all GlobalISel unittests use a hardcoded AArch64 target
machine. Factor this so I can write some for AMDGPU specific known
bits unittests.

Don't unnecessarily use ASSERT_*, and print the MachineFunction
on failure.
