ce2a0814 - [parse-sil] Refactor huge per op code parsing switch into its own method.

[parse-sil] Refactor huge per op code parsing switch into its own method. Done using Xcode's refactoring engine! Should be NFC. I am going to turn this method into a visitor on the op code. NOTE: Xcode's refactoring engine messd with the whitespace, so I also ran this through git-clang-format.
