32c169dbdf Front-end: Warn for likely missed change in default precisions. 
This is part of the change to have desktop shaders respect precision
qualifiers on Vulkan, but since the defaults are all highp, and that's
different from ES fragment shaders, detect likely cases and warn about
them (but being careful to not be too noisy if it's unlikely to be a
problem).

4d535640e4 Front-End: Non-ES trigger for processing precision qualifiers. 
Initially non-functional: Have an independent test for whether to obey
precision qualifiers other than whether the profile is es.

conventions better.

9f9bad09b4 PP: Add missing atoms that effect -E mode. 
When preprocessing only, some tokens were emitted as <bad token>.
This fixes them to preserve their original content.

This supplants PR #182, with a correction and test results.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation. 
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

11e1a073f3 PP: Fix issue #407; handle empty identifier. 
The sequence

  #define m()
  int m"

creates a token of no length (a string of 0 size).  Protect
against a string of 0 size as well as the existing protect
against a null string.

73d4fb5bc5 PP: Fix issue #408: # as last character in macro. 
This would look ahead for a second #, for token pasting, and if not
found, backup one token.  This is fine, unless at the end of line,
which would backup the #, rather than the look ahead.

fea226ba43 HLSL: Add shape conversions for scalar -> vector assigments. 
Also, this allows turning on the error check for a failed assigment
when parsing.

This makes 39 HLSL tests have a working assignment that was previously
silently dropped, due to lack of this functionality.

8c8505c604 SPV: For AST interpolateAt* ops consuming a swizzle, invert the order. 
Apply the interpolation first, then apply the swizzle to the result,
the inverse of the order requested by the AST.  This fixes issue #411.

61d9fb9048 Semantics: 'invocations' defaults to 1, not 0. 
'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.
