- bots were complaining that the bit-field width was less than the width of the underlying type (note, underlying types of enums can not be bit-fields)
  - add static_asserts for TSS and TSW to ensure that the bit-fields can hold all the enumerators - and add comments next to the last enumerator warning not to reorder.

See https://reviews.llvm.org/rC321622 for the patch that introduced the warnings.

[NFC] Modernize enums TypeSpecifierWidth, TypeSpecifierSign & TypeSpecifierType into scoped enums with underlying types.
  - Since these enums are used as bit-fields - for the bit-fields to be interpreted as unsigned, the underlying type must be specified as unsigned.

Previous failed attempt - wherein I did not specify an underlying type - was the sum of:

Clang is inherently a cross compiler and can generate code for any target
enabled during build. It however requires to specify many parameters in the
invocation, which could be hardcoded during configuration process in the
case of single-target compiler. The purpose of configuration files is to
make specifying clang arguments easier.

A configuration file is a collection of driver options, which are inserted
into command line before other options specified in the clang invocation.
It groups related options together and allows specifying them in simpler,
more flexible and less error prone way than just listing the options
somewhere in build scripts. Configuration file may be thought as a "macro"
that names an option set and is expanded when the driver is called.

Use of configuration files is described in `UserManual.rst`.

  - the enum changes to TypeSpecifierType are breaking some tests - and will require a more careful integration.

Sorry about rushing these changes - thought I could sneak them in prior to heading out for new years ;)

(Re-submission of D39937 with fixed tests.)

Adjust wording for const-qualification mismatch to be a little more clear.

Also add another diagnostic for a ref qualifier mismatch, which previously produced a useless error (this error path is simply very old; see rL119336):

Before:
  error: cannot initialize object parameter of type 'X0' with an expression of type 'X0'

After:
  error: 'this' argument to member function 'rvalue' is an lvalue, but function has rvalue ref-qualifier

Revert r321504 "[X86] Don't accidentally enable PKU on cannon lake and icelake or CLWB on cannonlake."

I based that commit on what was in Intel's public documentation here https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf

Which specifically said CLWB wasn't until Icelake.

But I've since cross checked with SDE and it thinks these features exist on CNL and ICL. So now I don't know what to believe.

I've added test coverage of the current behavior as part of the revert so at least now have proof of what we're doing.

Summary:
Previsouly clang tried instantiating member initializers even if ctor
body was skipped, this caused spurious errors (see the test).
