Merge blocks in reducer (#2353)
Fixes #2120 

Enhanced the reducer so that it can merge blocks together, leveraging the functionality extracted from the block_merge pass in the optimizer.

98c67d3850 Fixed names in ifdefs and GetName functions that had been forgotten in a previous refactoring. Also shortened names of test files as those files test both the new 'finder' classes introduced in the refactoring, as well as the 'reduction pass' class; the shorter names capture both.

86d0d9be25 Refactored reducer so that the 'finding' functionality of a reduction pass are separated from the generic functionality for tracking progress of a pass. With this change, we now have a ReductionOpportunityFinder abstract class, with many subclasses for each type of reduction, and just one ReductionPass class, which has an associated finder. (#2321)
Sounds good.

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.

1cba9942bd Validate during reduction (#2194)
* Run validator during reduction.

* Added functionality to validate modules after each reduction step, and some tests to check this is working.  Also fixed an issue where reduction passes were not guaranteed to be executed at their minimum granularities.

4aeadc0199 Add RemoveOpNameInstruction reduction pass (#2187)
Add a spirv-reduce pass which removes OpName and OpMemberName instructions.

This is useful to enable other reduction passes, e.g. RemoveUnreferencedInstruction may not be able to remove an instruction creating an id whose only usage is an OpName for this id.
