Missing type qualifiers for multi-dimensional arrays

[eliasnaur]

When converting compute shaders to gles profile 310, glslcc converts multi-dimensional arrays to one-dimensionsal and adjusts index expressions accordingly. Unfortunately, the adjusting index multiplier constants lack type qualifiers, leading to load errors such as:

error: could not implicitly convert operands to arithmetic operator
error: operands to arithmetic operators must be numeric

Example:

$ cat binning.comp 
#version 450
layout(local_size_x = 256, local_size_y = 1) in;

shared uint bitmaps[8][256];

void main() {
    for (uint i = 0; i < 8; i++) {
        bitmaps[i][gl_LocalInvocationID.x] = 0;
    }
}
$ glslcc --compute binning.comp --lang gles --profile 310 -o blah && cat blah_cs
binning.comp
#version 310 es
layout(local_size_x = 256, local_size_y = 1, local_size_z = 1) in;

shared uint bitmaps[8 * 256];

void main()
{
    for (uint i = 0u; i < 8u; i++)
    {
        bitmaps[i * 256 + gl_LocalInvocationID.x] = 0u;
    }
}

Note how the constant 256 in i * 256 + gl_LocalInvocationID.x lacks a type qualifier; replacing it with 256u avoids the load error.
