Kito Cheng 47b1fa5fc4 [RISCV] Fix the include search path order between sysroot and resource folder (Recommit)
Resource folder[1] should include before sysroot[2] in general (Linux clang
toolchain, BareMetal clang toolchain, and GCC using that order), and that
prevent sysroot's header file override resource folder's one, this change is
reference from BareMetal::AddClangSystemIncludeArgs@BareMetal.cpp[3].

And also fix the behavior of `-nobuiltininc`.

[1] Include path from resource folder is something like this: `<toolchain-path>/lib/clang/13.0.0/include/`
[2] Include path from sysroot is something like this: `<toolchain-path>/riscv32-unknown-elf/include`

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
