Improvements to disassembly within PassManager (#4677)

* PassManager: Print errors occurring during disassembly

Otherwise one could be greeted by the following text when running
spirv-opt withe the `--print-all` flag:

    ; IR before pass wrap-opkill

    ; IR before pass eliminate-dead-branches

    ; IR before pass merge-return

With this commit, one will instead get:

    error: line 143: Invalid opcode: 400
    warning: line 0: Disassembly failed before pass wrap-opkill

    error: line 143: Invalid opcode: 400
    warning: line 0: Disassembly failed before pass eliminate-dead-branches

    error: line 143: Invalid opcode: 400
    warning: line 0: Disassembly failed before pass merge-return

* PassManager: Use the right target environment when disassembling

Disassembly would fail if features from a newer version of SPIR-V than
1.2 were used.
