tools arch x86: Sync the msr-index.h copy with the kernel sources
To pick up the changes in:
6650cdd9a8
("x86/split_lock: Enable split lock detection by kernel")
Warning: Kernel ABI header at 'tools/arch/x86/include/asm/msr-index.h' differs from latest version at 'arch/x86/include/asm/msr-index.h'
diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
Which causes these changes in tooling:

Now one can do:
perf trace -e msr:* --filter=msr==IA32_CORE_CAPS
or:
perf trace -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'
And see only those MSRs being accessed via:
# perf trace -v -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'
New filter for msr:read_msr: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
New filter for msr:write_msr: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
New filter for msr:rdpmc: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
