c++: Fix reuse of class constants [PR94453]
The testcase hit an ICE trying to expand a TARGET_EXPR temporary cached from
the other lambda-expression. This patch fixes this in two ways:
1) Avoid reusing a TARGET_EXPR from another function.
2) Avoid ending up with a TARGET_EXPR at all; the use of 'p' had become
<TARGET_EXPR<NON_LVALUE_EXPR<TARGET_EXPR ...>>>, which doesn't make any
sense.

NON_LVALUE_EXPR.
