Remove an unnecessary restriction.  MIsNeedChainEdge() should be checked even when scheduler AliasAnalysis is not
enabled.  A good chunk of the MIsNeedChainEdge() is logic that is valid and should be applied even for targets
that are not using for alias analysis.

llvm-profdata: Avoid undefined behaviour when reading raw profiles

The raw profiles that are generated in compiler-rt always add padding
so that each profile is aligned, so we can simply treat files that
don't have this property as malformed.

Caught by Alexey's new ubsan bot. Thanks!

[llvm-objdump] support -rebase option for mach-o to dump rebasing info

Similar to my previous -exports-trie option, the -rebase option dumps info from
the LC_DYLD_INFO load command. The rebasing info is a list of the the locations
that dyld needs to adjust if a mach-o image is not loaded at its preferred 
address. Since ASLR is now the default, images almost never load at their
preferred address, and thus need to be rebased by dyld.
