It looks like there is a LTO code-size regression on trunk:
(size of libxul.so, build without elfhack):

gcc lto/pgo : size: 42204584 | Kraken bench: 2723.9ms +/- 0.9%
gcc         : size: 34072808 | Kraken bench: 2804.3ms +/- 1.6%
clang lto   : size: 35071848 | Kraken bench: 2804.2ms +/- 1.2%
clang       : size: 36797384 | Kraken bench: 2819.6ms +/- 1.4%
