This function is similar to cpu_msr_driver_open(), but with core number as parameter
For Linux, core number was always 0. To be able to get all core temp/voltage, we need to set the core number.
They have L3 cache, and the detection code incorrectly assumed this is a Xeon
Irwindale variant due to an old and no longer valid classification check.
Correctly handle the XEON_IRWIN subcode and add an entry in the matchtable
to fix Sandy Bridge-E Xeon.
- move the INLINE_ASM_SUPPORTED guards outside the body of exec_cpuid, as
suggested by Genoil;
- copy the asm code of busy_sse_loop to masm-x64.asm. Some fixup was
required, because the microsoft calling convention doesn't expect
xmm6 & xmm7 to be clobbered in functions.
Confirmed that --clock-ic from cpuid_tool works with the resulting library.

Priously all fields in the matchtable were treated equal in importance.
With this change, the cache size a taken with half the weight in the decision.
Also add detection entries for some more recent Haswells, and the respective
tests. These are an i5 Haswell from a Mac Book Pro, and a i7 Haswel from
Thinkpad T540.
- Detect AVX and AVX2 on both Intel and AMD CPUs
- Detect BMI1 and BMI2 instruction sets (BMI2 is only on Haswell, BMI1 is
also present on Bulldozers).
- Fix tests to reflect changes.
The last change to flags detection caused a bunch of tests to fail.
The reason is that they are bogus, all recent Intel chips don't have
RDTSCP indicated in the test files, whereas they have it in reality.
I figured it will be easier to add "--fix" option to run_tests.py,
rather than fixing each testfile by hand.
This is also extended in the Makefile:
"make test" runs the tests and reports discrepancies.
"make fix-tests" fixes any offending tests. This blindly assumes that
libcpuid is sane.
Previously the detection only tested this AMD CPUs and the table check was
only present in recog_amd.c
Thanks to Andrew Roberts for reporting this issue!
