7cf12c7efd reimplement Constant::ContainsRelocations as 
Constant::getRelocationInfo(), which has a much simpler
to use API.  It still should not be part of libvmcore, but
is better than it was.  Also teach it to be smart about 
hidden visibility.

5d8f1cae76 Fixing cp island pass. Step 1: Determine whether the constant pool offset can be 
negative on an individual bases rather than basing on whether it's in thumb
mode.

97d2cae44b Now that RelocBehaviour() is never overloaded, it doesn't need to be 
virtual.  Just inline it into its two current call sites in preparation
for simplifying the code.

cb45963643 add an API so target-independent codegen can determine if a constant 
pool entry will require relocations against it.  I implemented this
conservatively for ARM, someone who is knowledgable about it should
see if this can be improved.

117c7e2a6a remove the last bits of SectionFlagsForGlobal. There is some flag here that 
depends on XS1A, but I think the ReadOnlySection is already set up for this
and there is no testcase that this breaks.  If this is really needed, we can
add the appropriate parameterization to TargetAsmInfo in the future to support
this.

97ee12755d remove the Xcore implementation of SelectSectionForGlobal. While you have 
to twist your brain to see it, I believe it is the same as ELFTargetAsmInfo::SelectSectionForGlobal.

e1abeb478a Remove the XCore custom implementation of MergeableConstSection, relying on 
the generic ELF version instead.  This will result in its mergable constant
sections getting named ".rodata.cst4" instead of ".cp.const4", but the
linker looks at the section flags, not the name of the section AFAICT.

b3e7171926 Remove shift amount flavor. It isn't actually complete enough to 
be useful, and it's currently unused.  (Some issues: it isn't actually 
rich enough to capture the semantics on many architectures, and
semantics can vary depending on the type being shifted.)
