f5ba3d0c - [clang] Fix computeTypeLinkageInfo for dependent member pointers (#136689)

[clang] Fix computeTypeLinkageInfo for dependent member pointers (#136689) MemberPointerType may refer to a dependent class (qualifier), for which getMostRecentCXXRecordDecl returns NULL. It seems that the compiler never executed this code path before patch #136128 where the issue was reported. LIT tests 74 and 75 are reduced from Chromium and LLVM libc test harness as reported in #136128.
