This patch removes llvm::is_trivially_{copy/move}_constructible in
favor of std::is_trivially_{copy/move}_constructible.

The previous attempt to remove them in Dec 2020,
c8d406c93c5bb01599990201f78d8428dd29d289 <https://reviews.llvm.org/rGc8d406c93c5bb01599990201f78d8428dd29d289>, broke builds with "some
versions of GCC" according to
6cd9608fb37ca2418fb44b57ec955bb5efe10689 <https://reviews.llvm.org/rG6cd9608fb37ca2418fb44b57ec955bb5efe10689>.

It's been 20 months since then, and the minimum requirement for GCC
has been updated to 7.1 from 5.1.

FWIW, I was able to build llvm with gcc 8.4.0.
