With Control-Flow Integrity (CFI), the LowerTypeTests pass replaces function references with CFI jump table references, which is a problem for low-level code that needs the address of the actual function body. For example, in the Linux kernel, the code that sets up interrupt handlers needs to take the address of the interrupt handler function instead of the CFI jump table, as the jump table may not even be mapped into memory when an interrupt is triggered. This change adds the no_cfi constant type, which wraps function references in a value that LowerTypeTestsModule::replaceCfiUses does not replace.

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.
