Danylo Piliaiev c432cb672a glsl/linker: Fix attempts to split up 64bit varyings between slots 
When packing varyings when there is only 32bit of space
left in slot 64bit type is attempted to be divided between
current and next slot. However there is neither code for
splitting the 64bit type nor for assembling it back.
Instead we add 32bit padding.

The above happens only in structs because their
members aren't sorted by packing order.

Example of the issue:

struct S {
 vec3 a;
 double d;
};
out flat S s;

Before, the packing went as:

slot 32b  32b  32b  32b
 0   a.x  a.y  a.z   d
 1    d    0    0    0

After:

slot 32b  32b  32b  32b
 0   a.x  a.y  a.z   0
 1    d    d    0    0
