-												Add type information to integral template argument if required.

Non-comprehensive list of cases:
 * Dumping template arguments;
 * Corresponding parameter contains a deduced type;
 * Template arguments are for a DeclRefExpr that hadMultipleCandidates()

Type information is added in the form of prefixes (u8, u, U, L),
suffixes (U, L, UL, LL, ULL) or explicit casts to printed integral template
argument, if MSVC codeview mode is disabled.
