Place load after OpPhi instructions in block. (#2246)
We currently place the load instructions at the start of the basic block
that dominates all of the loads.  If that basic block contains OpPhi
instructions, then this will generate invalid code.  We just need to
search for a location that comes after all of the OpPhi instructions.

Fixes #2204.

Fixes #1281

* New structured cfg check: all non-construct header blocks'
predecessors must come from within the construct
* New function to calculate blocks in a construct

* Fixed a bug in BasicBlock type bitset

Relaxing check to not consider unreachable predecessors

* Fixing broken common uniform elim test

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

83228137e1 Re-format source tree - NFC.
Re-formatted the source tree with the command:

$ /usr/bin/clang-format -style=file -i \
    $(find include source tools test utils -name '*.cpp' -or -name '*.h')

This required a fix to source/val/decoration.h.  It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.

f4b29f3bf7 Add CommonUniformElim pass
- UniformElim: Only process reachable blocks

- UniformElim: Don't reuse loads of samplers and images across blocks.
  Added a second phase which only reuses loads within a block for samplers
  and images.

- UniformElim: Upgrade CopyObject skipping in GetPtr

- UniformElim: Add extensions whitelist
  Currently disallowing SPV_KHR_variable_pointers because it doesn't
  handle extended pointer forms.

- UniformElim: Do not process shaders with GroupDecorate

- UniformElim: Bail on shaders with non-32-bit ints.

- UniformElim: Document support for only single index and add TODO.
