Diana Picus a7372f15c9 [globalisel][tablegen] Skip src child predicates ... The GlobalISel TableGen backend didn't check for predicates on the source children. This caused it to generate code for ARM patterns such as SMLABB or similar, but without properly checking for the sext_16_node part of the operands. This in turn meant that we would select SMLABB instead of MLA for simple sequences such as s32 + s32 * s32, which is wrong (we want a MLA on the full operands, not just their bottom 16 bits). This patch forces TableGen to skip patterns with predicates on the src children, so it doesn't generate code for SMLABB and other similar ARM instructions at all anymore. AArch64 and X86 are not affected.
