When data is packed into uniform blocks, some data isn't formatted in
a way that fits how data is usually represented, which is the case
for booleans and row major matrices. In these 2 cases, the variables
are unpacked into temporaries before being used. Booleans can be any
integer value and any non-zero value represents "true", so the value
in the uniform buffer has to go through an int to bool conversion
before being used. For row major matrices, a given register of that
matrix has to be transposed into a temporary before being used.

This cl adds 2 new utility function and adds one use of
these in the argument() function.
- getBlockId() finds a block by name and returns its ID
- getTypedMemberInfo() finds which block member matches
  a certain register index and returns the block member's
  packing information and type. If the register falls
  within a block member (as a sub-register of a matrix or
  an array), the base offset of the block member is
  returned, along with the register index, which will then
  be used within the argument() function to compute the
  final parameter index.
