[COMMITTED] Inline unsupported_range constructor.

[Aldy Hernandez via Gcc-patches]

An unsupported_range temporary is instantiated in every Value_Range
for completeness sake and should be mostly a NOP.  However, it's
showing up in the callgrind stats, because it's not inline.  This
fixes the oversight.
