Summary: One of the conclusions of the discussion on D49740 was that SafeMachO is better off in the Host module (as that's the only place which should include mach/machine.h, which is what this header is working around). Also, Utility, which is the only module which cannot include Host, should not be doing anything with object file formats. This patch implements that move, and also removes any unneded includes of that file. I've verified that MacOS still compiles after this.

// This is the DynamicLoader plugin for Darwin (macOS / iPhoneOS / tvOS /

|
// watchOS)
|
|
// platforms late 2016 and newer, where lldb will call dyld SPI functions to get
|
|
// information about shared libraries, information about the shared cache, and
|
|
// the _dyld_debugger_notification function we put a breakpoint on give us an
|
|
// array of load addresses for solibs loaded and unloaded. The SPI will tell us
|
|
// about both dyld and the executable, in addition to all of the usual solibs.
