Fix go/ab builds for jb-mr1

splitting the initialization between init_array and ctors.

Local builds do this anyway, but for some reason the builds on go/ab do not.

ETC2 decoder

A new ETC2 decoder was added to SwiftShader, based on the
OpenGL ETC2 specification. The decoder is fully standalone
and does not rely on any outside code (there are no files
included in the header and the source file only include the
header file, so it can easily be ported to any other project).

Things to note:
- In Surface.cpp, signed ETC2 images are decoded to full 32FP
  images, because of the lack of support for signed 8 bit R
  and RG internal formats. This should be fixed as soon as
  these formats are made available.
- sRGB conversion is not performed within the decoder, so it has
  been added as a loop inside Surface::decodeETC2 after the ETC2
  decoding is performed. This is to make sure that there is no
  loss of precision, should we choose to do the conversion to a
  higher bit precision format. The loop is fairly straightforward
  and does the conversion in place, so the impact on performance
  compared to doing the sRGB conversion in the decoder should be
  minimal.

Matrix determinant and inverse implementation

For now, the implementation for the inverse matrix is very

Fixed non square matrix multiplication

A few cases of matrix multiplication weren't working properly
due to using the wrong matrix dimension. For example, if we
have the following matrix operation (using matColRow):
mat32 = mat22 * mat32
This results in 3 multiplication of 2 element vectors for each
row of the result and the current code (before this cl) would
only perform 2 multiplications and produce the wrong result.

This cl should fix all uses of the * operator and of the
matrixCompMult function when using non square matrices.

Fixed Temporary issues

Some issues, like failures using the do-while command, were caused
by the assembler being unable to assign registers consistently for
a single temporary variable. For example, in the do-while case, the
"iterate" Temporary object was not being assigned to the same
register between it's initial declaration and it's usage inside the
loop condition later on, causing the do-while to behave weirdly.
Other instances where multiple Temporary objects ended up being used
simultaneously of where a single object was references in multiple
parts of the code could have failed because of this.

The fix is simply to assign Temporary objects a unique ID.
