Make host valgrind work with clang/llvm.
Bug: 28454823
* Add -fno-builtin-memset flag.
Bug: 31035712
* Make esp 16-byte aligned before calling x86 functions.
Bug: https://bugs.kde.org/show_bug.cgi?id=368120
Note that this does not fix other errors on x86 emulator.
Change-Id: Ibc19d0902aaba68edbb9f3758da368c35294128b
