Accelerate utest.

For some test cases which include more than one kernel, the current
implementation always build the program for a new sub test case.

That wastes a lot of time. This patch introduce a new macro
MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM which has an extra parameter
to specify whether to keep the previous program and avoid the extra
build. The normal usage is:

MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM(fn1, true);
MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM(fn2, true);
MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM(fn3, true);
MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM(fn4, true);
MAKE_UTEST_FROM_FUNCTION_KEEP_PROGRAM(fn5, false);

The scenario is that the above fn1-5 are included in the same kernel
file and we define the sub cases in the same cpp file. We already
have some examples of this usage in the compiler_abs.cpp, compiler_abs_diff.cpp
compiler_basic_arithmetic.cpp, compiler_vector_load_store.cpp, etc.

This patch reduces 2/3 of the utests execution time.

v2: should always destroy the program when run one specific test case.
