  [X86] Remove X86RegisterInfo::getSEHRegNum. (#106866)

As far as I can tell, there's no way to call this. There are no calls in
the X86 directory. It has the same name as a function in MCRegisterInfo,
but that function takes a MCRegister and isn't virtual.

The function in MCRegisterInfo uses a DenseMap populated by
`X86_MC::initLLVMToSEHAndCVRegMapping`. The DenseMap is populated for
every physical register using the encoding value. I think that means the
function in MCRegisterInfo would return the same value as the function
in X86RegisterInfo.
