reduce: Add two branch reduction passes (#2507) 
* Fix #2320. `conditional_branch_to_simple_conditional_branch` reduction pass changes conditional branches so both targets point to the same block id (creating a "simple" conditional branch).
* Fix #2501. `simple_conditional_branch_to_branch` reduction pass changes "simple" conditional branches to branches. 
* Fix #2503. `conditional_branch_to_simple_conditional_branch` proper handling of back-edges.

71aa48f91d spirv-reduce: add OperandToUndefReductionPass (#2200) 
* Add OperandToUndefReductionPass.

Fixes #2115.

Also added some tests that are similar to those in OperandToConstantReductionPassTest.

In addition, refactor FindOrCreateGlobalUndef into reduction_util.cpp. Fixes #2184.

Removed many documentation comments that were identical or very similar to the overridden function's documentation comment.
