  Changed paths:
    M clang/lib/CodeGen/CGExprConstant.cpp
    M clang/test/CodeGenCXX/cxx20-consteval-crash.cpp

  Log Message:
  -----------
  Restrict lvalue-to-rvalue conversions in CGExprConstant.

We were generating wrong code for cxx20-consteval-crash.cpp: instead of
loading a value of a variable, we were using its address as the
initializer.

Found while adding code to verify the size of constant initializers.
