97f7ab865a Fix handling of NoWrite/NoRead decoration for images. 
The old workaround for glslang is no longer needed, so only apply workaround
carefully.

e27a5f7df6 CompilerMSL refactored to simplify handling of vertex attributes. 
Combine all vertex attributes into a single stage_in structure.
Remove unneeded structure members from MSLConfiguration, MSLVertexAttr and Meta::Decoration.
Remove unneeded CompilerMSL functions that supported struct offsets and padding.

a2b8a0e5c9 Refactor emit_texture_op() function. 
CompilerGLSL add to_function_name() and to_function_args() functions to organize
structure of emit_texture_op() function.
CompilerMSL add support for MSL gather(), gather_compare() and sample_compare() functions.

MSL enhancements

7d38f1822a CompilerMSL fixes to support pull-request feedback. 
Make Compiler::OpcodeHandler and Compiler::traverse_all_reachable_opcodes protected
instead of private, for use by subclasses.
Add CompilerMSL::CustomFunctionHandler and traverse_all_reachable_opcodes() to detect
active opcodes that require the output of a custom function.
CompilerMSL::custom_function_ops use std::set to retain ordering to improve testability.

32ae2eceed CompilerMSL enhancements to handling of in/out variables. 
CompilerMSL sort in/out attributes by attribute number (location). Sort inputs in reverse order.
CompilerMSL propagate incoming vertex attribute offset values.
CompilerMSL elide unused in/out variables.
CompilerMSL replace use of sets with unordered_sets.

e73e8e4f48 Add support for the BuiltInClipDistance builtin for MSL. 
CompilerGLSL builtin_to_glsl() function outputs gl_ClipDistance for BuiltInClipDistance
builtin, and includes builtin code in output when handling unknown builtin code.
CompilerMSL uses type ID instead of type object where appropriate to support array types,
where type.self is not consistent with actual type ID, plus support array stride calc
even when not explicitly set by SPIR-V code.
For output consistency, CompilerMSL prefers use of standard builtin names over specified
names, and output builtins qualified with output struct while in entry function.

4a05dcaeca Add Travis build 
Builds on both Linux and OSX and tests all shaders for regressions. The
shader set currently does not include any Metal shaders but once it does
we should be able to also validate the resulting MSL using Xcode metal
compiler.

e67f6f85a4 Defer parenthesis generation until needed. 
Previously, we would generate parentheses proactively when generating
binary ops, however, this leads to uglier code and hits warnings in
compilers when used as a conditional.
