  [X86] Add CPU name strings to getIntelProcessorTypeAndSubtype and getAMDProcessorTypeAndSubtype in compiler-rt.

These aren't used in compiler-rt, but I plan to make a similar
change to the equivalent code in Host.cpp where the mapping from
type/subtype is an unnecessary complication. Having the CPU strings
here will help keep the code somewhat synchronized.

  -----------
  [X86] Add CPU string output to getIntelProcessorTypeAndSubtype/getAMDProcessorTypeAndSubtype in Host.cpp

Rather than converting type/subtype into strings, just directly
select the string as part of family/model decoding. This avoids
the need for creating fake Type/SubTypes for CPUs not supported
by compiler-rtl. I've left the Type/SubType in place where it matches
compiler-rt so that the code can be diffed, but the Type/SubType
is no longer used by Host.cpp.

compiler-rt was already updated to select strings that aren't used
so the code will look similar.

  Log Message:
  -----------
  [X86] Remove model number based detection for 'pentiumpro', 'pentium2', 'pentium3', 'pentium-m', and 'yonah' from getHostCPUName.

For model 6 CPUs, we have a fallback detection method based on
available features. That mechanism should be enough to detect
these early family 6 CPUs as they only differ in the features
used by the detection anyway.
