Extend TableGen instruction selection matcher to improve handling

of complex instruction operands (e.g. address modes). Currently, if a Pat pattern creates an instruction that has a complex operand (i.e. one that consists of multiple sub-operands at the MI level), this operand must match a ComplexPattern DAG pattern with the correct number of output operands. This commit extends TableGen to alternatively allow match a complex operands against multiple separate operands at the DAG level. This allows using Pat patterns to match pre-increment nodes like pre_store (which must have separate operands at the DAG level) onto an instruction pattern that uses a multi-operand memory operand, like the following example on PowerPC (will be committed as a follow-on patch): def STWU : DForm_1<37, (outs ptr_rc:$ea_res), (ins GPRC:$rS, memri:$dst), "stwu $rS, $dst", LdStStoreUpd, []>, RegConstraint<"$dst.reg = $ea_res">, NoEncode<"$ea_res">; def : Pat<(pre_store GPRC:$rS, ptr_rc:$ptrreg, iaddroff:$ptroff), (STWU GPRC:$rS, iaddroff:$ptroff, ptr_rc:$ptrreg)>; Here, the pair of "ptroff" and "ptrreg" operands is matched onto the complex operand "dst" of class "memri" in the "STWU" instruction.
