cb309d27c5 intel/ir: Fix invalid type aliasing with undefined behavior in test_eu_compact.
test_fuzz_compact_instruction() was attempting to modify the uint64_t
data array of a brw_inst through a pointer to uint32_t, which has
undefined behavior.  This was causing the test_eu_compact unit test to
fail mysteriously for me on GCC 7 with some additional
harmless-looking changes I had applied to my tree, which happened to
affect the order instructions are emitted by GCC causing the bit
twiddling to be done after the clear_pad_bits() call which is supposed
to overwrite the same data through a pointer of different type,
leading to data corruption.  A similar failure has been reported by
Vinson Lee on the master branch built with GCC 8.

3d661e6062 i965: Test instruction compaction on all supported Gens
Note that there's no point in testing on G45, since its compaction is
the same as Gen5. Same logic applies to Gen7 variants and low-power
parts.

bdc5036464 intel/compiler: link all tests again gtest, even test_eu_compact"
At the moment all the tests but test_eu_compact are actual C++ gtests.
To simplify things, we can move the gtest.la to the common TEST_LIBS.
As we're here, we can rename change the test extension [to .cpp] to
avoid using the confusing dummy.cpp.

Add a nice comment in the makefile for posterity.
