867451f49e Add scalar replacement
Adds a scalar replacement pass. The pass considers all function scope
variables of composite type. If there are accesses to individual
elements (and it is legal) the pass replaces the variable with a
variable for each composite element and updates all the uses.

Added the pass to -O
Added NumUses and NumUsers to DefUseManager
Added some helper methods for the inst to block mapping in context
Added some helper methods for specific constant types

No longer generate duplicate pointer types.

* Now searches for an existing pointer of the appropriate type instead
of failing validation
* Fixed spec constant extracts
* Addressed changes for review
* Changed RunSinglePassAndMatch to be able to run validation
 * current users do not enable it

Added handling of acceptable decorations.

* Decorations are also transfered where appropriate

Refactored extension checking into FeatureManager

* Context now owns a feature manager
 * consciously NOT an analysis
 * added some test
* fixed some minor issues related to decorates
* added some decorate related tests for scalar replacement

5d602abd66 Add global redundancy elimination
Adds a pass that looks for redundant instruction in a function, and
removes them.  The algorithm is a hash table based value numbering
algorithm that traverses the dominator tree.

This pass removes completely redundant instructions, not partially
redundant ones.
