0ebb88cc39 MSL: Redirect member indices when buffer has been sorted by Offset.
If a buffer rewrites its Offsets, all member references to that struct
are invalidated, and must be redirected, do so in to_member_reference,
but there might be other places where this is needed. Fix as required.
SPIR-V code relying on this is somewhat questionable, but seems to be
in-spec.

a5d82d1138 Alter the handling of spec consts in non-Vulkan GLSL
Previously, when generating non-Vulkan GLSL, each use of a spec constant
would be subsituted for its default value and the declaration of the constant
itself would be omitted completely.

This change slightly alters this behavior. The uses of the constant are kept,
as well as the declaration, although the latter is stripped of the layout
qualifier. The declaration is also prepended with the following code:

    #ifndef <constant name>_value
    #define <constant name> <default constant value>
    #endif

and the constant itself now looks like

    const <constant type> <constant name> = <constant name>_value;

The rationale for this change is that it gives the user a way to provide
custom values for specialization constants even when the target does not
support them.

991b655c72 Declare OpSpecConstantOp up-front on relevant targets.
Required, since spec constants can include results from constant ops.
