1890f2f0e2 x86: Move cpuinfo.h from libgcc to common/config/i386 
Both x86 backend and libgcc define enum processor_features.  libgcc sets
enum processor_feature and x86 backend checks enum processor_feature.
They are very easy out of sync and it has happened multiple times in the
past.

1. Move cpuinfo.h from libgcc to common/config/i386 so that we can share
the same enum processor_features in x86 backend and libgcc.
2. Change __cpu_features2 to an array to support more processor features.
3. Add more processor features to enum processor_features.

abd0cdc9c0 Hide __cpu_indicator_init/__cpu_model from linker 
We shouldn't call external function, __cpu_indicator_init, while an object
is being relocated since its .got.plt section hasn't been updated.  It
works for non-PIE since no update on .got.plt section is required.  This
patch creates libgcc.so as a linker script, hides __cpu_indicator_init
and __cpu_model in libgcc.so.1 from linker, forces linker to resolve
__cpu_indicator_init and __cpu_model to their hidden definitions in
libgcc.a while providing backward binary compatibility.
