Fixes#854. But, only good if we are not trying to use the same
texture for both shadow and non-shadow constructors.
Force the type of the texture to have 'shadow' set when it is
constructed with a samplerShadow.
This is one step in providing full linker functionality for creating
correct SPIR-V from multiple compilation units for the same stage.
(This was the only remaining "hard" part. The rest should be simple.)
These introduce limited support for 8/16-bit types such that they can only be accessed in buffer memory and converted to/from 32-bit types.

Constant.cpp will throw a floating point divide by zero if floating point exceptions are enabled in Win32 causing the program to crash. This fix manually checks the right-hand argument of the division and sets appropriate Infinity, Negative Infinity, or NAN as if the floating point exceptions were disabled.
TDefaultIoResolverBase::reserveSlot and getFreeSlot now have a size
parameter to reserve a range of bindings. This is used by
TDefaultIoResolver::resolveBinding to reserve a continuous range when
the type is an array and the target API is GL.
Fixes#1228. Fixes#234.
This uses imbue() to be locale independent. Notes:
- 'sstream >> double' is much slower than strtod()
* this was measurable in the test suite as a whole, despite being
a tiny fraction of what the test suite does
- so, this embeds a fast path that bypasses sstream most of the time
=> the test suite is faster than before
- sstream is probably slower, because it does more accurate rounding than strtod()
- sstream does not create INFINITY by itself, this was done based on failure inferencing
- Adds a pragma to see binary output of double values (not portable)
- Print decimals that show more values, but in a portable way
(lots of portability issues)
- Expand the tests to test more double values
Note: it is quite difficult to have 100% portable tests for floating point.
The current situation works by not printing full precision, and working around
several portability issues.
The transform removes sampler arguments from functions and function
calls; this causes function arguments to change their indices. When some
function arguments have an output qualifier, this qualifier can get lost
because of the removal which can lead to incorrect results (e.g. out
qualifier not having effect).
To fix this we iterate through both seq & qual arrays in lock-step and
manually remove/replace entries as appropriate.
When assigning a location to an interface whose stage automatically
converts the interfaces to an array, it now strips off the outermost
array from the type before calculating how many locations it consumes.
