Petar Avramovic 416346d1ca AMDGPU/GlobalISel/Emitter Recognize additional 'same operand checks'
The "name" of a non-leaf complex pattern (MY_PAT $op1, $op2) is
"MY_PAT:op1:op2" and the ones with same "name" represent same operand.
Add 'same operand check' for this case.

Jessica Paquette f41ce85909 [GlobalISel][NFC] Factor out common target code from GlobalISelEmitterTests
Factor out commonly-used target code from the GlobalISelEmitter tests into
a GlobalISelEmitterCommon.td file. This is tested by the original
GlobalISelEmitter.td test.

This reduces the amount of boilerplate code necessary for tests like this.

Jessica Paquette 1ed1dd6d95 [GlobalISel] Skip patterns that define complex suboperands twice instead of dying
If we run into a pattern that looks like this:

add
  (complex $x, $y)
  (complex $x, $z)

We should skip the pattern instead of asserting/doing something unpredictable.

This makes us return an Error in that case, and adds a testcase for skipped
patterns.
