Fix the nSVM MSR interception test to actually detect failures, and expand
its coverage to test:
- Out-of-range MSRs
- With all other bits in the MSPRM clear
- {RD,WR}MSR with interception *disabled*
- That L1 and L2 see the same value for RDMSR when interception is disabled

Sean Christopherson (8):
x86: nSVM: Actually report missed MSR intercepts as failures
x86: nSVM: Test MSRs just outside the ranges of the MSR Permissions
Map
x86: nSVM: Clean up variable types and names in test_msr_intercept()
x86: Expand the suite of bitops to cover all set/clear operations
x86: nVMX: Use set_bit() instead of test_and_set_bit() when return is
ignored
x86: nSVM: Set MSRPM bit on-demand when testing interception
x86: nSVM: Verify disabling {RD,WR}MSR interception behaves as
expected
x86: nSVM: Verify L1 and L2 see same MSR value when interception is
disabled
