egl/x11: Free memory allocated for reply structures on error

This patch fixes memory leaks when reply is allocated and is not freed
on error execution path.

Found by enabling address sanitizer on simple EGL app.

```c

int main()
{
    EGLDisplay display = eglGetDisplay(EGL_DEFAULT_DISPLAY);
    EGLint major;
    EGLint minor;

    if (!eglInitialize(display, &major, &minor))
    {
        return 1;
    }
    eglTerminate(display);
    return 0;
}
```

Compiled with: `gcc testme.c -o testme -fsanitize=address -lasan -lEGL`

spirv: fix emitting switch cases that directly jump to the merge block

As shown in the valid SPIR-V below, if one switch case statement
directly jumps to the merge block, it has no branches at all and
we have to reset the fall variable. Otherwise, it creates an
unintentional fallthrough.

This fixes serious corruption in Horizon Zero Dawn.

v2: Changed the code to skip the entire if-block instead of resetting
    the fallthrough variable.

This doesn't really do anything for us today.  One day, I suppose we
could use it to do something with wide loads with non-uniform offsets.
The big reason to do this is to get better testing to make sure that NIR

nir/lower_io: Apply alignments from derefs when available

If the deref has no explicit alignment in the chain, we assume component
alignment which is what we currently assume for all derefs today.  This
should be correct for all APIs in the sense that we can usually assume
at least component alignment.  However, for some APIs such as OpenCL, we
could potentially make larger alignment assumptions.  The intention is
that those will be handled via alignment-increasing casts.

nir/glsl: Add an explicit_alignment field to glsl_type

When creating explicit type, the alignment information is lost, thus
forcing explicit type users to recalculate the alignment using the same
size_align() function. Let's add a new field to cache this information.

Only structs, matrices, and vectors have and explicit alignment.  Arrays
alignment is implicitly set to its element alignment and matrices are
required to have an alignment that matches that of its vector columns.
the concept of alignment simply doesn't apply to other types.

We make the strategic choice to not allow explicit alignments on
scalars.  This is for a couple of reasons:

 1. There are no cases today where we use explicit types where we want
    any other alignment for scalars than natural alignment.

 2. Vectors don't have a component alignment that's separate from the
    explicit_alignment so it's impossible to get an explicitly aligned
    scalar type which is the component of the explicitly aligned vector
    type.

This choice may cause problems if we ever want to use explicitly laid
out types for things like varyings where we sometimes want vec4
alignment of scalars.  We can deal with that when the time comes.
