Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.

Enables xsave/xrstor by turning on cr4.osxsave on cpu's which have
the xsave support. For now, features that OS supports/enabled are
FP and SSE.

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.
The format:
1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
underscores.

This breaks up the mutual inclusion between headers ptrace.h and vm86.h
by moving some small part of vm86.h which is needed by ptrace.h into
processor-flags.h.
We also try to move #include lines to the top.
This has been compile tested on x86_32 and x86_64 defconfig, and run
through 'make headers_check'.

This patch is based on Rusty's recent cleanup of the EFLAGS-related
macros; it extends the same kind of cleanup to control registers and
MSRs.
It also unifies these between i386 and x86-64; at least with regards
to MSRs, the two had definitely gotten out of sync.

Move X86_EFLAGS_IF et al out to a new header: processor-flags.h, so we
can include it from irqflags.h and use it in raw_irqs_disabled_flags().
As a side-effect, we could now use these flags in .S files.
