Tong Zhang 17ce89fa80 [SanitizerBounds] Add support for NoSanitizeBounds function
Currently adding attribute no_sanitize("bounds") isn't disabling
-fsanitize=local-bounds (also enabled in -fsanitize=bounds). The Clang
frontend handles fsanitize=array-bounds which can already be disabled by
no_sanitize("bounds"). However, instrumentation added by the
BoundsChecking pass in the middle-end cannot be disabled by the
attribute.

The fix is very similar to D102772 that added the ability to selectively
disable sanitizer pass on certain functions.

In this patch, if no_sanitize("bounds") is provided, an additional
function attribute (NoSanitizeBounds) is attached to IR to let the
BoundsChecking pass know we want to disable local-bounds checking. In
order to support this feature, the IR is extended (similar to D102772)
to make Clang able to preserve the information and let BoundsChecking
pass know bounds checking is disabled for certain function.

These are syntax highlighting files for the Emacs and XEmacs editors. Included
are:

* llvm-mode.el

  Syntax highlighting mode for LLVM assembly files. To use, add this code to
  your ~/.emacs :

  (setq load-path
    (cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
  (require 'llvm-mode)
  
* tablegen-mode.el

  Syntax highlighting mode for TableGen description files. To use, add this code
  to your ~/.emacs:

  (setq load-path
    (cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
  (require 'tablegen-mode)


Note: If you notice missing or incorrect syntax highlighting, please contact
<llvm-bugs [at] lists.llvm.org>; if you wish to provide a patch to improve the
functionality, it will be most appreciated. Thank you.
