Ben Clayton 32cb9cf2f8 tint/writer: Disable constant inlining for lets
Once 'const' is introduced, let will no longer resolve to a
creation-time constant value.

Add temporary code into each of the writers to prevent constants that
originate from a 'let' from being inlined. This will reduce the amount
of noise in later CLs.
