adds a resource limit for very large multibits.

68bf473e2e fdr: move long literal handling into Rose 
Move the hash table used for long literal support in streaming mode from
FDR to Rose, and introduce new instructions CHECK_LONG_LIT and
CHECK_LONG_LIT_NOCASE for doing literal confirm for long literals.

This simplifies FDR confirm, and guarantees that HWLM matchers will only
be used for literals < 256 bytes long.

a08e1dd690 Introduce a 64-bit LimEx model. 
On 64-bit platforms, the Limex 64 model is implemented in normal GPRs.
On 32-bit platforms, however, 128-bit SSE registers are used for the
runtime implementation.

6899cab370 unit-internal: fix FDR issues reported by ASan 
FDR's streaming mode now assumes that it is safe to read 16 bytes before
the end of the history buffer, and this was not reflected in the unit
tests.
