6ab3d582d6 Preprocessor: 1) Rationalize the "fixed atom" scheme, 2) remove redundant lookups when the text is already available. 
This simplification is a prelude to eliminating what I appear unnecessary
symbol inserts into tables when tokenizing in the preprecessor, which
show up as taking notable time. (Performance issue.)  It also simply makes
the preprocessor easier to understand, which it is badly in need of.

Preprocessing directive handling

aae1ad8296 Added error output to the preprocessor. 
This patch distinguishes preprocessing errors with normal parsing
errors and gives glslangValidator the ability to output preprocessing
errors.

46ea5396ef Fix empty line handling in line directive callback. 
The current line number for the #line directive should be passed
in as parameter to the line directive callback. Without it, we
don't know how many empty lines we should output.

5cbc990a0a Fix line number handling in line directive callback. 
The line argument passed into the lineCallback function is the
literal value of the first argument of the #line directive.
lastLine in DoPreprocessing() should be updated taking into
consideration the different definitions for #line between specs.

Add a test to reveal the bug.

68d78fd31e Updated command-line options, adding -o for saving binaries, -G for OpenGL SPIR-V validation, -v etc. 
Old uses should still work as they did before.
Also encapsulated use of these flags during parsing, for the parse context.
Added SPIR-V version to -v.

cf0206c341 Restore r26245 and all tests and test results since 4/1: 
r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

fcb4ed054c Preprocessor: Rationalize, simplify, and correct the stack of input sources and their tokenization. This included 
- consistently dealing with EOF and its effect on error recovery (bug 11444, #1)
 - turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy
 - correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself
 - conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not
 - delete some unused "memory cleanup" code

4d6570a1b3 Fix several issues in the preprocessor: 
- macro expansion of hexidecimal numbers 
 - give errors instead of warnings/silence on extra tokens after #endif, #else, etc.
 - give errors on reserved macro name use, reuse of argument, and redefinition with different whitespace presence
 - detect and give error for all cases of #elif and #else after #else
