[PATCH, v2]: AMD btver1 and btver2 enablement

[Eggone, NagaJyothi]

Hello,

I did not receive any reviews for the patch I submitted last week.
I made some changes in the patch format and test files and am submitting again.
Please review and if found OK, please commit the patch on my behalf.

NOTE: I have omitted the diffs in the generated files opcodes/i386-init.h and opcodes/i386-tbl.h in the patch.
So please use --enable-maintainer-mode to test the patch.

Thanks,
Nagajyothi

Subject: [PATCH]:AMD btver1 and btver2 enablement

Hello Maintainers,

I have added the basic support for AMD's low power btver1 and btver2 cores.
I have added the cpu_arch entries for btver1 and btver2, and defined respective CPU_BTVER*_FLAGS.
As part of btver1 enablement, 3dnow instructions prefetch and prefetchw are also extended. 

I have tested on x86_64-unknown-linux-gnu. If it is OK for trunk, please commit on my behalf.

NOTE: I have omitted the large diffs in the generated files opcodes/i386-init.h and opcodes/i386-tbl.h in the patch.
So please use --enable-maintainer-mode to test the patch.

Thanks,
Nagajyothi
