[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.

Function member (test74):

    MemberPointerType 'type-parameter-0-0 (type-parameter-0-1::*)(void)' dependent
    |-TemplateTypeParmType 'type-parameter-0-1' dependent depth 0 index 1
    `-FunctionProtoType 'type-parameter-0-0 (void)' dependent cdecl
      `-TemplateTypeParmType 'type-parameter-0-0' dependent depth 0 index 0

Template parameter (test75):

    MemberPointerType 'type-parameter-0-1 type-parameter-0-0::*' dependent
    |-TemplateTypeParmType 'type-parameter-0-0' dependent depth 0 index 0
    `-TemplateTypeParmType 'type-parameter-0-1' dependent depth 0 index 1

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
