  [clang] Add clang::nooutline Attribute

This change:
- Adds a `[[clang::nooutline]]` function attribute for C and C++. There
  is no equivalent GNU syntax for this attribute, so no `__attribute__`
  syntax.
- Uses the presence of `[[clang::nooutline]]` to add the `nooutline`
  attribute to IR function definitions.
- Adds test for the above.

The `nooutline` attribute disables both the Machine Outliner (enabled at
Oz for some targets), and the IR Outliner (disabled by default).
