SPIR-V: Aggressively prune unreachable merge, continue target

More aggressively prune unreachable code as follows. When no control flow edges reach a merge block or continue target: - delete their contents so that: - a merge block becomes OpLabel, then OpUnreachable - a continue target becomes OpLabel, then an OpBranch back to the loop header - any basic block which is dominated by such a merge block or continue target is removed as well. - decorations targeting the removed instructions are removed. Enables the SPIR-V builder post-processing step the GLSLANG_WEB case.
