Remove using std::<foo> statements. (#1756)
Many of the files have using std::<foo> statements in them, but then the
use of <foo> will be inconsistently std::<foo> or <foo> scattered
through the file. This CL removes all of the using statements and
updates the code to have the required std:: prefix.

28199b80b7 Fix block ordering in dead branch elim
Fixes #1727

* If the pass finds any dead branches it can optimize then at the end of
the pass it reorders basic blocks to ensure they satisfy block ordering
requirements
 * Added some new tests
* While investigating this issue, found and fixed a non-deterministic
ordering of dominators
 * Now the edges used to construct the dominator tree are sorted
 according to posorder traversal indices

045cc8f75b Fixes compile errors generated with -Wpedantic
This patch fixes the compile errors generated when the options
SPIRV_WARN_EVERYTHING and SPIRV_WERROR (that force -Wpedantic) are
set to cmake.

d2938e4842 Re-format files in source, source/opt, source/util, source/val and tools.
NFC. This just makes sure every file is formatted following the
formatting definition in .clang-format.

Re-formatted with:

$ clang-format -i $(find source tools include -name '*.cpp')
$ clang-format -i $(find source tools include -name '*.h')

fef669f30f Add a new class opt::CFG to represent the CFG for the module.
This class moves some of the CFG-related functionality into a new
class opt::CFG.  There is some other code related to the CFG in the
inliner and in opt::LocalSingleStoreElimPass that should also be moved,
but that require more changes than this pure restructuring.

I will move those bits in a follow-up PR.

Currently, the CFG is computed every time a pass is instantiated, but
this should be later moved to the new IRContext class that @s-perron is
working on.

Other re-factoring:

- Add BasicBlock::ContinueBlockIdIfAny. Re-factored out of MergeBlockIdIfAny
- Rewrite IsLoopHeader in terms of GetLoopMergeInst.
- Run clang-format on some files.

b25b330069 Inline: Create CFA class
Create class to encapsulate control flow analysis and share across
validator and optimizer. A WIP. Start with DepthFirstTraversal. Next
pull in CalculateDominators.
