8d63a3d35a Avoid read past end of operands vector for EOpFrexp 
When emitting SPIR-V code for frexp, avoid access
beyond the end of the operands vector.  When constructing
the OpExtInst, construct a new arguments vector instead of
modifying the existing operands vector.  In the case of OpFrexp,
well need that last operand later on to generate the store.

08dee03d18 Remove include_directories from CMakeLists, to enforce relative includes 
* This also moves bison generated files into the source tree, so that
  include of glslang_tab.cpp.h and includes from glslang_tab.cpp work
  the same way.

2d83ab2f57 Fixed subtle issue that causes tests to fail in VS2013 in some configs. 
Depending on specific optimization settings VS2013 will sometimes
execute the operands to

new Instruction(builder.getUniqueId(), builder.makeBoolType(), OpPhi)

left-to-right, and sometimes right-to-left. Since makeBoolType can
also call getUniqueId(), the IDs to the OpPhi can sometimes be swapped.

This guarantees an explicit ordering of the Ids so that tests work
reliably.

e770b3e6cf SPV return from main: Simplify a legacy design such returns are not jumps to exit block. 
Structured control-flow rules allow leaving the middle of a construct through
a return, but not through a jump to a block that does a return.

Addresses issue #58.

fa668dad99 SPV: Reduce spurious type generation by removing intermediate types in the middle of access chains. 
This generally simplifies access chain generation, with far fewer  type conversions.
It is particularly important to future SPIR-V changes where there is less aggregate
type uniqueness due to carrying different layout information with the type.

There's nothing really special about texelFetch other than the opcode and
some restrictions so adding it is pretty trivial.

fc51d284aa Backward incompatible: Turn on PureOperatorBuiltins: use only enum-based built-in functions in the AST. 
If this breaks your AST consumer, best is to modify it to test
against the enum values instead of doing string comparisons on
built-in function names.  This is the reason the change was made.

If you need the old behavior, you should be able to get it back by changing
PureOperatorBuiltins to be false instead of true.  This path will work for
a while, but is marked deprecated.

Also, the old behavior is tagged as release 2.4.
