Implement matrix inverse built-in
Inverse is emulated in HLSL by calculating the cofactor matrix and
dividing that with the determinant. This results in the transpose of the
inverse as is required. Better performing options might exist especially
for 4x4 matrices, but this is enough for a working implementation.

Implement hyperbolic function support for ESSL 3.00
Emulating arc hyperbolic functions is required on HLSL, where they do
not exist natively. For this, BuiltInFunctionEmulator is split into GLSL
and HLSL subclasses. The GLSL subclass handles the pre-existing built-in
emulation implemented for working around OSX bugs, and the HLSL subclass
handles emulating asinh, acosh and atanh on HLSL.

Remove RemoveAllTreeNodes, since it was a no-op
IntermNode operator delete() or any of the IntermNode destructors don't
do anything, since all the AST memory is allocated on the PoolAllocator.
Because of this, RemoveAllTreeNodes was simply a no-op, and redundant
with the PoolAllocator deallocation procedure, and could confuse people
reading the code to think that IntermNodes should be deleted
individually, when in fact this is not the case.

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.

Fix precision tracking for built-in function return values
Previously, the type of the return value of all function calls was set to
the type of the return value in the function signature. This did not
carry precision information.
This patch changes this so that the return value precision is set
correctly for built-in functions. For single-argument math functions, it
mostly depends on that addUnaryMath sets the type of the return value to
be the same as the type of the operand. The type is replaced but the
precision information from the operand type is retained when needed. For
multi-argument math functions, precision is determined based on all the
nodes in the aggregate after the type has been set. For texture
functions, the precision is set according the sampler type as per ESSL
1.0 spec. For textureSize, the precision is always highp as per ESSL 3.0
spec.
