plugins/cache: supported multicore cache modelling
...
Multicore L1 cache modelling is introduced and is supported for both
full system emulation and linux-user.
For full-system emulation, L1 icache and dcache are maintained for each
available core, since this information is exposed to the plugin through
`qemu_plugin_n_vcpus()`.
For linux-user, a static number of cores is assumed (default 1 core, and
can be provided as a plugin argument `cores=N`). Every memory access
goes through one of these caches, this approach is taken as it's
somewhat akin to what happens on real setup, where a program that
dispatches more threads than the available cores, they'll thrash
each other

plugins/cache: Fixed a bug with destroying FIFO metadata
...
This manifests itself when associativity degree is greater than the
number of sets and FIFO is used, otherwise it's also a memory leak
whenever FIFO was used.

eviction policies can be chosen as an argument. On not specifying an
argument, LRU is used by default.

plugins: Added a new cache modelling plugin
...
Added a cache modelling plugin that uses a static configuration used in
many of the commercial microprocessors and uses random eviction policy.
The purpose of the plugin is to identify the most cache-thrashing
instructions for both instruction cache and data cache.
