use -Xclang -debug-info-kind=constructor if available
The option, available since Clang10, emits debuginfo for classes
with explicit ctors only together with the ctor, which avoids
redundant debuginfo for such classes, noticeably saving both build
time and disk space. https://reviews.llvm.org/D72427
I've been using this for quite some time, without problems.
