The optimization as done in opt_copy_propagation would have to be
removed in the next patch. If we just eliminate that optimization
altogether, shader-db results, even on platforms that use NIR, are hurt
quite substantially. I have not investigated why NIR isn't picking up
the slack here.

Instead of generating a sequence like:
run_default = true;
if (i == 3) // some label that appears after default
run_default = false;
if (i == 4) // some label that appears after default
run_default = false;
...
if (run_default) {
...
}
generate something like:
run_default = !((i == 3) || (i == 4) || ...);
if (run_default) {
...
}
This eliminates one use of conditional assignment, and it enables the
elimination of another.

The values being compared are scalars, so these are the same. While
I'm here, simplify the run_default condition to just deref the flag
(instead of comparing a scalar bool with true).
There is a bit of extra change in this patch. When constructing an
ir_binop_equal ir_expression, there is an assertion that the types are
the same. There is no such assertion for ir_binop_all_equal, so
passing glsl_type::uint_type with glsl_type::int_type was previously
fine. A bunch of the code motion is to deal with that.

This happens to work now because ir_binop_all_equal is used. This
causes vector typed init-expressions to produce scalar Boolean values
after comparison.
The next commit changes ir_binop_all_equal to ir_binop_equal. Vector
typed init-expressions will then produce vector Boolean values, and, in
debug builds, the ir_assignment constructor will fail an assertion.

After get_variable_being_redeclared() has been called, it is no longer
safe to access the original variable pointer, since its memory might have
been freed.
Since callers of this function should only be accessing the variable pointer
returned by the function, avoid potential bugs by re-assigning the
original variable pointer to the result of the function call,
making it impossible for the remaining code to access an invalid variable
pointer.

get_variable_being_redeclared() can delete the original variable
in a specific scenario. The code sets it to NULL after this so other
code in that same function doesn't try to access trashed memory after
the fact, however, the copy of that variable in the caller code
won't see any of this making it very easy to overlook.
Make the function a bit safer by taking a pointer to the original
variable so we can also make NULL the caller's pointer to the variable
if this function deletes it.
