a76766a434 getBaseAlignment: Use the rowMajor argument for determining matrix strides 
The argument version is passed in from above and struct handling ensures
that row-majorness gets propagated correctly from one level to the next.
If we just look at the type itself and it's embedded in a struct that's
declared row-major, we may get the wrong stride.

e602d25f09 Removed strcpy that copied to itself. 
Found by running glslang with -fsanitize=address in clang.
Also fixes a potential buffer-overrun with return from lReadByte.

778b876587 Add .clang-format. 
This allows automatic source-file formatting with clang-format, freeing
contributors from worrying about formatting while keeping the style
consistent everywhere.

dba2826328 Merge branch 'master' of github.com:google/glslang into loopgen

832c65c33b Fix back-branch target for do-while loops. 
To ensure back branches always go to a header block, create a header
block even for !testFirst loops.  Then unify common code between the
testFirst/!testFirst cases.

Generate the header-block code first, so update golden files.

Realize that certain infinite loops generate invalid SPIR-V, so put a
TODO to instead abort code generation in such cases.

7ba6341a05 SPV: Make OpEntryPoint I/O list include all static uses. 
Before, it was only including explicit interface, sufficient for IO-Block-declared
oriented interface, but not sufficient for all modes GLSL might be used with
SPIR-V.

Two things are accomplished now:
1) each id will appear exactly once
2) the OpEntryPoint list will union static use with declarations

61d9fb9048 Semantics: 'invocations' defaults to 1, not 0. 
'invocations' was using 0 as the "shader never set" flag and as the
