[WebAssembly] Split and recombine multivalue calls for ISel
Summary: Multivalue calls both take and return an arbitrary number of
arguments, but ISel only supports one or the other in a single
instruction. To get around this, calls are modeled as two pseudo
instructions during ISel. These pseudo instructions, CALL_PARAMS and
CALL_RESULTS, are recombined into a single CALL MachineInstr in a custom
emit hook.
RegStackification and the MC layer will additionally need to be made
aware of multivalue calls before the tests will produce correct output.

[GISelKnownBits] Make the max depth a parameter of the analysis
Allow users of that analysis to define the cut off depth of the analysis
instead of hardcoding 6.
NFC as the default parameter is 6.
