I actually miss this option, maybe we can bring it back some day.

Add the __ARM_ARCH_EXT_IDIV__ predefine. It is set to 1 if we have hardware divide in the mode that we are compiling in (depending on the target features), not defined if we don't. Should be compatible with the GCC conterpart. Also adding a -hwdiv option to overide the default behavior.

This adds support for outputing the assembly to a file during compilation.
It does this by changing the compilation pipeling to not use the integrated
assembler, and keep the intermediate assembler file.

Some build systems use pipes for stdin/stderr. On nix-ish platforms colored
output can be forced by -fcolor-diagnostics. On Windows this option has
no effect in these cases because LLVM uses the console API (which only
operates on the console buffer) even if a console wrapper capable of
interpreting ANSI escape codes is used.

The -fansi-escape-codes option allows switching from the console API to
ANSI escape codes. It has no effect on other platforms.

DataFlowSanitizer is a generalised dynamic data flow analysis.

Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own.  Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting
levels for parentheses, brackets and braces.

Some code with heavy macro use exceeds the default limit of 256, but we don't
want to increase it generally to avoid stack overflow on stack-constrained
systems.

implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

Clang doesn't understand it.

If someone wants to teach clang about that flag instead, please also add
support for -fno-diagnostics-parseable-fixits for consistency.

Until then, let the documentation match the current behavior.
