[DebugInfo][InstrRef] Prefer stack locations for variables ...
This patch adjusts what location is picked for a known variable value --
preferring to leave locations on the stack, even when a value is re-loaded
into a register. The benefit is reduced location list entropy, on a
clang-3.4 build I found that .debug_loclists reduces in size by 6%, from
29Mb down to 27Mb.
Testing: a few tests need the stack slot to be written to explicitly, to
force LiveDebugValues into restoring the variable location to a register.
I've added an explicit test for the desired behaviour in
livedebugvalues_recover_clobbers.mir .
