Hi.

The following patch fixes detection of VENDOR_CENTAUR CPU vendors when 
-march=native is used.
Problem what that BUILTIN_VENDOR_MAX dropped the current enum value to 
VENDOR_OTHER (4)
and thus VENDOR_MAX was 5 and not 7.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
I'm going to push it as obvious.

    gcc/ChangeLog:
    
            * common/config/i386/i386-cpuinfo.h (enum processor_vendor):
              Reorder enum values as BUILTIN_VENDOR_MAX should not point
              in the middle of the valid enum values.
