[PATCH] D62009: [clang] perform semantic checking in constant context

[Tyker via Phabricator via cfe-commits]

Tyker added a comment.

i added this bit because when we eventually store the result of evaluation in ConstantExpr we will probably want to trail-allocate the APValue's possible representations separately to limit memory consumption. but if we do this the ConstantExpr node will need to be created after evaluation of the value, so we cannot use it to mark that the expression should be evaluated in constant context.
if we won't store APValue's possible representations separately in trail-allocate space, wrapping the expression in a ConstantExpr is the right solution.
