[GlobalISel] convergent intrinsics

Introduced the convergent equivalent of the existing G_INTRINSIC opcodes:

- G_INTRINSIC_CONVERGENT
- G_INTRINSIC_CONVERGENT_W_SIDE_EFFECTS

Out of the targets that currently have some support for GlobalISel, the patch
assumes that the convergent intrinsics only relevant to SPIRV and AMDGPU.
