Enable SPIR-V disassembly output from skslc. We now have SPIR-V golden outputs for `blend` and `shared` tests. This exposes a handful of SPIR-V limitations for us to address.

Deduplicate vector constants in SPIR-V output. Many of our shaders generate the same vector constant dozens of times, e.g. Gaussian blur uses float4(1) repeatedly. This change avoids re-emitting redundant vector constants.

Perform the loop-exit test when continuing from inside a do-while. SPIR-V would previously jump to the top of the do-while loop when encountering a `continue`. This is not correct; it should jump to the loop-exit test. We don't have any real shaders which test this case, and it can't be checked from inside Runtime Effects since do-while is not part of ES2.
