756da12ae4 Don't forget D16 - D31 are clobbered by calls and sjlj eh.

4a8b7d030b Add R12 to the list of registers clobbered by 16-bit Thumb calls as a pre-caution. r12 could be live once we have mixed 32-bit and 16-bit instructions.

298414ec18 remove the SelectSectionForMachineConst hook, replacing it with 
a new getSectionForMergableConstant hook.  This removes one dependence
of TAI on Type, and provides the hook with enough info to make the 
right decision based on whether the global has relocations etc.

fc6ad402fb Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it. 
This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

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.

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

semantics can vary depending on the type being shifted.)
