The "uniform-work-group-size" function attribute previously took a string value of "true" or "false". Since presence alone can convey the "true" semantics and absence can convey "false", the value is unnecessary. This patch converts it to a valueless string attribute: presence indicates true, absence indicates false. For backward compatibility, auto-upgrade logic is added in both UpgradeAttributes (bitcode) and UpgradeFunctionAttributes: if the old value is "true", the attribute is kept without a value; if "false", the attribute is removed.
