+Summary: [PATCH] decompose complex opcodes before BURG
+An opcode such as CEE_LDLEN should be decomposed before BURG sees it. When
+we decompose the operation, BURG is able to see that the ldlen is really
+LD_IND_I4 (base). It can use this information to combine the operation into
+another assembly instruction (for example, it can do cmp DWORD PTR
+[eax+length_offset], 5)
