[Bug target/40735] New: [4.3/4.4 regression] memory hog compiling big functions with -fPIE

Building the attached file with gcc from the 4.4 branch with -g
-fstack-protector -fPIE -Os, the build fails (killed by oom), last info seen is
memory usage of about 1500mb. Building without -fPIE memory usage is limited
around 700MB.

Same behaviour for 4.3. With gcc-4.2 peak memory usage is with/without -fPIE
below 400MB. Not checked on trunk, currently fails to build.
