Evan Cheng e0b3c221ab Add a target lowering hook to control whether it's worthwhile to compress fp constant. ... For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive. llvm-svn: 47931		2008-03-05 01:30:59 +00:00
