Summary This option can be used to reduce the size of the
binary. The trade-off in this case would be the run-time
performance.

Summary:
This updates all places in documentation that refer to "Mac OS X", "OS X", etc.
to instead use the modern name "macOS" when no specific version number is
mentioned.
If a specific version is mentioned, this attempts to use the OS name at the time
of that version:
* Mac OS X for 10.0 - 10.7
* OS X for 10.8 - 10.11
* macOS for 10.12 - present

be statically linked into a target binary executable.

Since the attribute documentation is now auto-generated, the previous references
are no longer valid. This prevented the docs build from completing
successfully.

- Added the description of the interceptor suppression.
- Re-organized a bit: grouped a few things under the Issue Suppression
section, grouped IOC and leaks under a section, placed symbolication
info into Symbolizing the Reports section..
- In supported platforms: "MacOS" -> "OS X"; added "iOS Simulator"
- Added a paragraph to the Usage section describing when DYLD_INSERT_LIBRARIES
might need to be used.
- "attribute((no_sanitize_address))" -> "__attribute__((no_sanitize("address")))"
- Updated Leak Sanitizer page with most up to date info.

They autotools build has a number of missing features, supports less
OS, architectures, build configurations, doesn't have any tests and
is hard to support in sync with CMake build.

This commit changes the way we blacklist global variables in ASan.
Now the global is excluded from instrumentation (either regular
bounds checking, or initialization-order checking) if:
1) Global is explicitly blacklisted by its mangled name.
This part is left unchanged.
2) SourceLocation of a global is in blacklisted source file.
This changes the old behavior, where instead of looking at the
SourceLocation of a variable we simply considered llvm::Module
identifier. This was wrong, as identifier may not correspond to
the file name, and we incorrectly disabled instrumentation
for globals coming from #include'd files.
3) Global is blacklisted by type.
Now we build the type of a global variable using Clang machinery
(QualType::getAsString()), instead of llvm::StructType::getName().
After this commit, the active users of ASan blacklist files
may have to revisit them (this is a backwards-incompatible change).

These are two related changes (one in llvm, one in clang).
LLVM:
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory
CLANG:
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))
for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S
