This reverts commit r310630.
The new code broke on Windows and was untested. On Linux, it was
selecting the "int" overload of operator<<, which definitely does not
print the right thing when fed a "Mode" char.
llvm-svn: 310661
Summary:
1. Refactor the structure of the code by adding a base class for all close-on-exec checks, which implements most of the needed functions.
2. memfd_create() is better to set MFD_CLOEXEC flag to avoid file descriptor leakage.

Summary:
This patch renames checks, check options and changes messages to use correct
term "implicit conversion" instead of "implicit cast" (which has been in use in
Clang AST since ~10 years, but it's still technically incorrect w.r.t. C++
standard).

Prepend the clang library directory (determined using SHLIBDIR, alike
in clang) to the LD_LIBRARY_PATH to ensure that just-built clang
libraries will be used instead of a previous installed version.
When a stand-alone build is performed, LLVM_LIBS_DIR contains the path
to installed LLVM library directory. The same directory frequently
contains a previously installed version of clang. SHLIBDIR, on the other
hand, is always the build-tree directory, and therefore contains
the freshly built clang libraries.
In a non-stand-alone build, both paths will be the same and therefore
including them both will not cause any issues.

[clang-tidy] clang-apply-replacements: Don't insert null entry
Fix crash when running clang-apply-replacements on YML files which
contain an invalid file path. Make sure we never add a nullptr into the
map. The previous code started adding nullptr to the map after the first
warnings via errs() has been emitted.

Created new module bugprone and placed the check in that.
Finds memset() calls with potential mistakes in their arguments.
Replaces and extends the existing google-runtime-memset-zero-length check.
Cases covered:
* Fill value is a character '0'. Integer 0 might have been intended.
* Fill value is out of char range and gets truncated.
* Byte count is zero. Potentially swapped with the fill value argument.

Tests would go flaky if;
1. Using %T (not %t)
2. Put a file with common name like header.h into %T
3. Other tests (eg. misc-unused-parameters.cpp) are doing as well
We should avoid using %T unless it really makes sense.

For the following code: `modernize-use-override` generates a replacement with incorrect location.
```
struct IntPair

};
struct A

virtual void il(IntPair);
};
struct B : A
{
void il(IntPair p = {1, (2 + 3)}) {};
// Generated Fixit: void il(IntPair p = override {1, (2 + 3)}) {};
// Should be: void il(IntPair p = {1, (2 + 3)}) override {};
};
```
This fixes that and adds a unit test.
