Consider adding test coverage for /Zc:alignedNew-

[StephanTLavavej]

Currently, we have no test coverage for /Zc:alignedNew- aside from the feature-test macros test:

STL/tests/std/tests/VSO_0157762_feature_test_macros/env.lst

Line 36 in 3c13e3e

PM_CL="/MT /std:c++latest /permissive- /EHsc /Zc:alignedNew- /DTEST_DISABLED_ALIGNED_NEW"

As C++17/20 without over-aligned allocation is an unusual mode, we can break it - see #1689. We should consider adding test coverage, but we need to think about the best way to do so - adding distinct configurations is expensive.
