[Beignet] [PATCH] utests: Added unit tests to test LLVM and ASM dump generation.

[Sirisha Gandikota]

This patch adds 2 new tests to the unit tests. It uses the existing 
framework and data structures and tests the llvm/asm dump generation
when these flags (-dump-opt-llvm, -dump-opt-asm) are passed as build 
options along with the dump file names.

Methods added:
1) get_build_llvm_info() tests LLVM dump generation
2) get_build_asm_info() tests ASM dump generation
