This has added comments to spill-related instructions and added @plt to
some symbols.
Differential Revision: https://reviews.llvm.org/D92841
Most of the test changes are trivial instruction reorderings and differing
register allocations, without any obvious performance impact.

The SplitF64 node is used on RV32D to convert an f64 directly to a pair of i32
(necessary as bitcasting to i64 isn't legal). When performed on a ConstantFP,
this will result in a FP load from the constant pool followed by a store to
the stack and two integer loads from the stack (necessary as there is no way
to directly move between f64 FPRs and i32 GPRs on RV32D). It's always cheaper
to just materialise integers for the lo and hi parts of the FP constant, so do
that instead.

To do this:
1. Change GlobalAddress SDNode to TargetGlobalAddress to avoid legalizer
split the symbol.
2. Change ExternalSymbol SDNode to TargetExternalSymbol to avoid legalizer
split the symbol.
3. Let PseudoCALL match direct call with target operand TargetGlobalAddress
and TargetExternalSymbol.
