c++: array new initialized from a call [PR99643]

Here the get_foo() call results in a TARGET_EXPR, which we strip in
massage_init_elt, but then when build_vec_init tries to use it to
initialize
the array element we crash because build_aggr_init expects a class rvalue
to
have a TARGET_EXPR.  So don't strip it.

The stripping was added in r206639 for PR59659, so I checked that removing
it didn't significantly increase compile time or memory usage for that
testcase; compile time was unaffected, memory usage increased by 0.4%.

gcc/cp/ChangeLog:

PR c++/99643
* typeck2.c (massage_init_elt): Don't strip TARGET_EXPR.

gcc/testsuite/ChangeLog:

PR c++/99643
* g++.dg/cpp0x/initlist-new5.C: New test.
