cpu: Add Haswell-noTSX-IBRS CPU model

Browse Source 
This is a variant of Haswell-noTSX with indirect branch prediction
protection. The only difference between Haswell-noTSX and
Haswell-noTSX-IBRS is the added "spec-ctrl" feature.

The Haswell-noTSX-IBRS model in QEMU is a bit different since
Haswell-noTSX got several additional features since we added it in
cpu_map.xml:
    arat, abm, f16c, rdrand, vme, xsaveopt

Adding them only to the -IBRS variant would confuse our CPU detection
code.
