The ensures that virtual registers always belong to an allocatable class.
If your target attempts to create a vreg for an operand that has no
allocatable register subclass, you will crash quickly.

This ensures that targets define register classes as intended.

-Wuninitialized gives this warning:

The second note lacks filename, line number, and code snippet.  This change
will remove the fixit and only point to variable declaration.

Adding a new 'type category disable *' feature that disables all categories - This is intended as a quick kill switch for data formatters for cases where the user wants as little extra processing as possible to be done on their target, or to override major data formatters bug, should they occur

For Intel Atom, use ILP scheduling always, instead of ILP for 64 bit
and Hybrid for 32 bit, since benchmarks show ILP scheduling is better
most of the time.

Driver: Turn the default value for -fmath-errno into a proper target hook and disable it by default on more platforms.

For now -fno-math-errno is the default on BSD-derived platforms (Darwin,
DragonFlyBSD, FreeBSD, NetBSD, OpenBSD). If the default is not right for
your platform, please yell. I only verified the result with the default
compilers on Darwin and FreeBSD.
