Revert "target-i386: Disable HLE and RTM on Haswell & Broadwell"
This reverts commit 13704e4c455770d500d6b87b117e32f0d01252c9.
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3
machine-types.
So instead of making the CPU model results confusing by making it depend
on the machine-type, keep HLE and RTM on the existing Haswell and
Broadwell CPU models. The plan is to introduce "Haswell-noTSX" and
"Broadwell-noTSX" CPU models later, for people who have CPUs that don't
have TSX feature available.

target-i386: Haswell-noTSX and Broadwell-noTSX
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3
machine-types.
So, to cover both cases, introduce Haswell-noTSX and Broadwell-noTSX CPU
models, for hosts that have Haswell and Broadwell CPUs without TSX support.
