Fix reachability in the validator (#3541)
Fixes #3529

* Make BasicBlock::reachable() only consider static reachability
* Fix reachability calculation to be independent of block order
* add tests

b334829a91 Validate nested constructs (#3068)
* Validate that if a construct contains a header and it's merge is
reachable, the construct also contains the merge
* updated block merging to not merge into the continue
* update inlining to mark the original block of a single block loop as
the continue
* updated some tests
* remove dead code
* rename kBlockTypeHeader to kBlockTypeSelection for clarity

Implement WebGPU specific CFG validation (#2386)
In WebGPU all blocks are required to be reachable, unless they are one of two
specific degenerate cases for merge-block or continue-target. This PR adds in
checking for these conditions.

Fixes #2068

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

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.

Move the validation code into the val:: namespace (#1682)
This CL moves the validation code to the val:: namespace. This makes it
clearer which instance of the Instruction and other classes are being
referred too.

Change libspirv to spvtools namespace (#1678)
This CL changes all of the libspirv namespace code to spvtools to match
the rest of the code base.

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.

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.

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')

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.

109ce225c9 Fixes bug #517.
entry_block_to_construct_ maps an entry block to its construct. The key
in this map (the entry block) is not unique, and therefore the entry for
the continue construct gets overwritten when the selection construct is
discovered.

Since a given block may be the entry block of different types of
constructs, the (basic_block, construct_type) pair should be able to
uniquely identify the construct.

Adds test:
- In this test, a basic block is the entry block of a continue construct
  as well as the entry block of a selection construct.
  It can be shown that this unit test would crash without the fix in this
  PR and passes with the fix in this PR.

6993fc413d Validation code for control flow nesting depth.
According to Section 2.17 (Universal Limits) of the SPIR-V Spec, the
control flow nesting depth may not be larger than 1023.

This is checked only when we are required to have structured
control flow.  Otherwise it's not clear how to compute control
flow nesting depth.
