Wang, Xin10 3657e7777f Add delete to fix resource leak in llc.cpp ...

From line 693 in file llc.cpp, it uses new operator to creates a ModulePass
and assigned to MMIWP. If the condition after take the true branch, it has
chance to go in to line 702 or line 709, the function will return without
cleaning the memory.
The second issue existed for the same reason, the ref TPC get the pointer
created from LLVMTM.createPassConfig, and will leak memory if goes into
line 709.
This patch uses delete in the issued branch.
