kib a1956e48c3 Update print_INTEL_TLB() by the tag values from the Intel SDM
rev. 55.  The modern CPUs cache and TLB descriptions looked quite
questionable without the update, e.g. Haswell i7 4770S reported:
	Data TLB: 4 KB pages, 4-way set associative, 64 entries
	L2 cache: 256 kbytes, 8-way associative, 64 bytes/line
After the update, the report is:
	Data TLB: 1 GByte pages, 4-way set associative, 4 entries
	Data TLB: 4 KB pages, 4-way set associative, 64 entries
	Instruction TLB: 2M/4M pages, fully associative, 8 entries
	Instruction TLB: 4KByte pages, 8-way set associative, 64 entries
	64-Byte prefetching
	Shared 2nd-Level TLB: 4 KByte/2MByte pages, 8-way associative, 1024 entries
	L2 cache: 256 kbytes, 8-way associative, 64 bytes/line
Some tags were apparently removed from the table 3-21, Vol. 2A.  Keep
them around, but add a comment stating the removal.

Update the format line for cpu_stdext_feature according to the bits
from the SDM rev.55.  It appears that Haswells do not store %cs and
%ds values in the FPU save area.

Store content of the %ecx register from the CPUID leaf 0x7
subleaf 0 as cpu_stdext_feature2 and print defined bits from it,
again acording to SDM rev. 55.
