Switch implementation
Implemented switch/case for glsl in OpenGL ES 3.0.
For simplicity, it is implemented as a loop without a condition,
so break statements work properly like so:
begin switch
if(...) // 1st case
...
else if(...) // other cases
...
else // default case
...
end switch // Anchor point for break statements
All related dEQP tests pass, except 7 tests where vertex shaders
contain a switch or a loop within another switch. These 7 failures
have only about 5% of bad pixel and seem to be related to an issue
with int(floor(...)), since the equivalent tests inside the fragment
shader pass.
KNOWN ISSUE: If a switch is within a loop and one of the cases
contains a "continue" statement, this will not be
handled correctly at the moment. There are no dEQP
tests for this at the moment, AFAIK.

Fixed some unary operators
There were a few issues in unary operators:
- Many were not compiling because the promote function had not
been adjusted to take the new builtin functions into account
- abs and sign had not been implemented for int
- For the integer abs version, used pabsd. Removed the extra
argument, which seemed unnecessary (abs should have 1 input,
1 output, AFAIK).

Passing uniform buffers to the vertex/pixel programs
This cl contains the necessary changes to make uniform buffers
usable in shaders. A few things to note:
- Uniform buffers can be set, but nothing will attempt to access
them in this cl.
- While the 'index' of uniforms is expressed in terms of registers,
uniform buffer 'index' is expressed in bytes in both PixelProgram
and VertexProgram. This is necessary because of packing which can
potentially put some variables in the middle of registers.
Technically, std140 always packs variables in multiples of byte4,
but other future layouts may not, so using bytes as the unit is
more future proof.
- The above mentioned 'index' will have to be computed in OutputASM
and extra operations will need to be added (to fetch a row from a
row major matrix, for example).

Texture function refactoring
To make it easier to branch on the different texture
fetching options, a new TextureFunction class is
introduced here, which performs the string comparisons
and identifies the different options.
I also had to add a 5th argument for textureGradOffset
and textureProjGradOffset.
I added function stubs (with the UNIMPLEMENTED markers)
for all new texture functions.

Matrix determinant and inverse implementation
Implementation for determinant has been done directly in
ShaderCore in order to avoid having to allocate temporaries
manually in OutputASM.
For now, the implementation for the inverse matrix is very
simple, i.e., it doesn't attempt to re-use results from the
cofactor matrix computation to compute the determinant or
do any other kind of optimization, but it works.

- Changing "char*" to "const char*" when a
function can receive string literals
- Removed some unused variables and members
- Fixed some signed vs unsigned comparisons
- Added braces for safety on code like:
if(...) if(...) ... else ...
to make it:
if(...) { if(...) ... else ... }
otherwise the else is ambiguous
- Reordered some member initializations to
fit the declaration order in the class
- OutDir must end with a backslash in VS
