Add support for pentium-m and prescott

Hi,
this patch adds support for pentium-m CPU (used by Centrino notebooks)
that is mostly like P3 but with SSE2 and new P4 with SSE3. Intel
marketing scheme is confusing enough to use same name for P4 and P4 with
SSE3 but they attach letter 'E' to the MHZ number, so I added it as
pentium4e.
I also added pentium3m and pentium4m so it will be hopefully cleaner that these
are not pentium-m.
I would like to put this patch into 3.4 and equivalent probabily into 3.3 too
as we have support for SSE3 there but no -march switch to enable it so we are
forcing users to use funny combinations of -msseX flags.
Bootstrapped/regtested i686-pc-gnu-linux. OK?
Honza
PS: What happent to the patch renaming PNI to SSA3 for mainline?

* config.gcc: Add support for pentium4e/pentium-m/pentium3m/pentium4m.
* i386.c (override_options): Add support for new CPUs.
* i386.h (TARGET_CPU_DEFAULT_NAMES): New names.
(TARGET_CPU_DEFAULT_pentium_m, TARGET_CPU_DEFAULT_pentium4e): New constants.
* invoke.texi: Extend documentation of -mtune/-march for new CPUs.
