  [clang] CodeGen: fix ConstantExpr LValue emission (#181057)

This fixes a regression introduced in #161029, though not the fault of
that patch, only by incidental changes regarding the preservation of
constant expression nodes.

The LValue emission of ConstantExpr was doing strange things with
regards to what type corresponds to the result of the constant
expression, which are not justified by any tests or in the discussions
of the relevant patches.

See

https://github.com/llvm/llvm-project/commit/09669e6c5fa1e8db9c1091cc264640fb0377d6b6
and https://github.com/llvm/llvm-project/pull/78041 and
https://github.com/llvm/llvm-project/commit/51e4aa87e05c45bebf9658a47980b1934c88be31

This simplifies it to just use the expression type.

Since this regression was never released, there are no release notes.

Fixes #177807
