[libc] Enable llvmlibc clang-tidy checks Summary: Add clang-tidy for llvm-libc source directory. Example of check in action: ``` /workspace/llvm-project/libc/src/string/strcpy.cpp:10:1: error: system include stdio.h not allowed [llvmlibc-restrict-system-libc-headers,-warnings-as-errors] #include <stdio.h> ^~~~~~~~~~~~~~~~~~ ``` Reviewers: sivachandra, abrachet Reviewed By: sivachandra, abrachet Subscribers: aheejin, MaskRay, tschuett, libc-commits Tags: #libc-project Differential Revision: https://reviews.llvm.org/D76559 2020-03-24 11:33:56 +08:00			`Checks: '-,llvmlibc-'`

[libc] Fix accidental inclusion of system libc headers. Summary: I found that because `--system-headers` flag was not included when running clang-tidy, errors produced from compiler provided headers were being suppressed. After passing this flag I realized that by including headers like stdint.h we were indirectly including headers from the system libc. To prevent this we pass `-ffreestanding`. We don't want to pass `--system-headers` for all checks just the `llvmlibc-restrict-system-libc-headers` therefore we do a separate invocation of clang-tidy for this check.
