* Previously the offset was only updated with EOpIndexDirectStruct, but we also
need to update it for the other index types into arrays, and when expanding an
aggregate reached after dereferencing.
* Make sure source strings are terminated
The source strings may or may not have a null terminator. We need to
make sure we add one before outputting the source strings as we iterate
over the c-str looking for the null terminator.
* Review feedback
As reported in #1624, Ubuntu 14.04 LTS still uses CMake 2.8.12 which
does not support the Threads::Threads target (added in CMake 3.1).
This could be reverted once the required CMake version is bumped to 3.1+.
Would typically be pthreads.
Without this, '-Wl,--no-undefined' would output these errors:

including SPV generation using SPV_EXT_fragment_invocation_density.
This is an alias of the functionality in SPV_NV_shading_rate, and thus in some
cases we can only have one set of the tokens present (switch statements), so
we have picked the EXT version. This required updating the expected test
results for SPV_NV_shading_rate.
Also updated the known-good for spirv-headers so that the validator in
spirv-tools knows about the new extension.
This change adds unary conversion folding when the source is a constant.
This fixes an ISV issue whereby:
```
const float16_t f = float16_t(42.0);
```
Wouldn't compile because the conversion operator would always produce an
EvqTemporary when it could have produced an EvqConst.
I've also added a test case that proves out that all basic-type to
basic-type conversions work.
If a block has assigned a XfbOffset it is assumed that it would
inherit the current global XfbBuffer. This commit fixes two use cases:
1) Getting the members of a Block with a XfbOffset to be assigned an
offset, as explained on GLSL 4.60 spec, section "4.4.2 Output
Layout Qualifiers", subsection "Transform Feedback Layout
Qualifiers".
2) Compute properly an error on overlapping ranges if a block is
assigned a XfbOffset and one of it members is assigned a explicit
one. This gets working because when the members of a block get
assigned a Offset/Buffer at fixBlockXfbOffsets, then the block is
deassigned the Offsets, so ranges are computed only with the block
members.
BTW, this is already done when redeclaring block builtins.
Fixes#1535
