ld: warning: pointer not aligned at address on iOS

[Jacob Carlborg]

So far I've been building LDC against upstream LLVM 9.0.0. When I build 
with the LDC fork of LLVM, 9.0.1 I a bunch of the following warnings 
when compiling the test runners for iOS:

ld: warning: pointer not aligned at address 0x10321E776 (anon + 1270 
from 
~/development/d/ios-druntime/ldc-build-runtime.tmp/lib/libphobos2-ldc-unittest-debug.a(uni.o))

ld: warning: pointer not aligned at address 0x1033AAFB3 (anon + 110 from 
lib/libdruntime-ldc-debug.a(ti_Areal.o))

I'm not sure if it's because it's LLVM 9.0.1 or if it's because the LDC 
fork.
