I suggest to include the message in this commit message on how to disable LTO for source level debug.
[BuildOptions]
XCODE:*_*_*_CC_FLAGS = -O0 -fno-lto
Thanks

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1202
Turn on LTO for XCODE.
We need to pass -object_path_lto <file> to the linker to keep source level debugging working.
