Subject: Make the new Objective-C "id" and "Class" redefinition types special
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d1571acc700b652a52c766e36a6c688d9bf6f3a1;p=clang

Make the new Objective-C "id" and "Class" redefinition types special
types that are preloaded by the PCH file. Fixes PCH breakage
introduced in r79248.
