PP: Implement locale-independent strtod, using istringstream and a fast path.

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

Fix TextureUpgradeAndSamplerRemovalTransform when used with qualifiers

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.

HLSL: allow self-type cast (as no-op passthrough)

Previously, casting an object of a struct type to an identical type
would produce an error.  This PR allows this case.

As a side-effect of the change, several self-type casts in existing
tests go away.  For example:

    0:10          Construct float ( temp float)
    0:10            'f' ( in float)

becomes this (without the unneeded constructor op):

    0:10          'f' ( in float)

For vector or array types this can result in somewhat less overall code.
