i386: Add the support for AMD EPYC 3rd generation processors
Adds the support for AMD 3rd generation processors. The model
display for the new processor will be EPYC-Milan.
Adds the following new feature bits on top of the feature bits from
the first and second generation EPYC models.
pcid : Process context identifiers support
ibrs : Indirect Branch Restricted Speculation
ssbd : Speculative Store Bypass Disable
erms : Enhanced REP MOVSB/STOSB support
fsrm : Fast Short REP MOVSB support
invpcid : Invalidate processor context ID
pku : Protection keys support
svme-addr-chk : SVM instructions address check for #GP handling

device-crash-test: Remove problematic language
Replace "whitelist" in the device-crash-test script with
"rule list".
I'm using "rule list" instead of "allow list" or "pass list"
because the list is not used only for expected/allowed errors.
It also contain rules specifying which errors shouldn't be
ignored and/or should be fatal.

Log Message:
-----------
hostmem: Don't report pmem attribute if unsupported
When management applications (like Libvirt) want to check whether
memory-backend-file.pmem is supported they can list object
properties using 'qom-list-properties'. However, 'pmem' is
declared always (and thus reported always) and only at runtime
QEMU errors out if it was built without libpmem (and thus can not
guarantee write persistence). This is suboptimal since we have
ability to declare attributes at compile time.
