<pre>Hi, i'm compiling llvm from github with some sanitizer obtions (in c++, c, and
ld), and if we set LLVM_BUILD_32_BITS=ON the compilation phase fails.
I'm using Gentoo 64, GCC-7.3.0
Sanitizer obtions: -fsanitize=undefined -fsanitize=shift
-fsanitize=shift-exponent -fsanitize=shift-base
-fsanitize=integer-divide-by-zero -fsanitize=unreachable -fsanitize=vla-bound
-fsanitize=null -fsanitize=return -fsanitize=signed-integer-overflow
-fsanitize=bounds -fsanitize=bounds-strict -fsanitize=object-size
-fsanitize=float-divide-by-zero -fsanitize=float-cast-overflow
-fsanitize=nonnull-attribute -fsanitize=returns-nonnull-attribute
-fsanitize=enum -fsanitize=vptr
