Fix structured exit validation (#3141)
Fixes #3139

* If the header of the construct is also a merge block, jump to the
associated header instead of the immediate dominator
  * prevents spurious failures from unrelated constructs
* new tests

Remove merge assert in block calculation (#2489)
Fixes #2488

* Validator doesn't identify back-edge of the loop, so the merge is
never set
* Construct::blocks() has safe uses of `merge` so the assert can be
removed
* Added a test

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.

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')
