* config/i386/cpuid.h: Define signature_*_e[bcd]x macros for
matching results of level 0 calls to __cpuid to processor
manufacturers.
* config/i386/driver-i386.c (vendor_signatures): Removed.
(processor_signatures): Removed.
(host_detect_local_cpu): Replace uses of now-removed SIG_*
constants with the new signature_*_ebx constants.
libstdc++-v3/
* src/c++11/random.cc (random_device::_M_init): Use new macro
signature_INTEL_ebx to check for Intel processors.
