Fix HiPE debug lock checking on OS X 64bit

Position-independent code is mandatory on OS X. We use r11 as an intermediate
register to fill BIF_P->hipe.bif_callee. This fixes the following error when
doing `make debug FLAVOR=smp`:

clang -cc1as: fatal error: error in backend: 32-bit absolute addressing is not supported in 64-bit mode
let Java compiler output all warnings
stdlib: Fix maps type pretty printing

Properly align union typed assoc values.
edoc, erl_docgen: Enhance internal map type format
erts: Fix erts app-file
ssh: Avoid timeout of init_per_test_case on some platforms

Also some code cleanup
ssh: Avoid windows wierdness
