This patch fixes a problem introduced by clang change https://reviews.llvm.org/D95617 and described by https://bugs.llvm.org/show_bug.cgi?id=50076#c6, where inlined functions omit unused parameters both in the stack trace and in `frame var` command. With this patch, the parameters are listed correctly in the stack trace and in `frame var` command. Specifically, we parse formal parameters from the abstract version of inlined functions and use those formal parameters if they are missing from the concrete version.
