Enable MSVS warning 4512.
Fix up the missing DISALLOW_COPY_AND_ASSIGN macros and various small
problems preventing us from turning on this warning. This should
ensure we more often use the DISALLOW macro going forward.

Add mediump and lowp precision emulation support for GLSL output
This implements the rounding as specified in WEBGL_debug_shader_precision
extension proposal for desktop GLSL and ESSL output. The bulk of the new
functionality is added in the form of a new EmulatePrecision AST
traverser, which inserts calls to the rounding routines angle_frm and
angle_frl in the appropriate places, and writes the rounding routines
themselves to the shader.
Compound assignments which are subject to emulation are transformed from
"x op= y" to "angle_compound_op_frm(x, y)", a call to a function which
does the appropriate rounding and places the result of the operation to
x.
The angle_ prefixed names should not clash with user-defined names if
name hashing is on. If name hashing is not on, the precision emulation
can only be used if the angle_ prefix is reserved for use by ANGLE.
To support the rounding routines in output, a new operator type is added
for internal helper function calls, which are not subject to name
hashing.
In ESSL output, all variables are forced to highp when precision
emulation is on to ensure consistency with how precision emulation
performs on desktop.
Comprehensive tests for the added code generation are included.

Invariant related processing.
* Fix a bug in PreProcessor for STDGL pragma.
* Record all invariant settings and set them in ShaderVariable.
