56fa3ce519 Change getRelocationAdditionalInfo to be ELF only.
It was only implemented for ELF where it collected the Addend, so this
patch also renames it to getRelocationAddend.

d175d83203 Add getSymbolAlignment to the ObjectFile interface.
For regular object files this is only meaningful for common symbols. An object
file format with direct support for atoms should be able to provide alignment
information for all symbols.

This replaces getCommonSymbolAlignment and fixes
test-common-symbols-alignment.ll on darwin. This also includes a fix to
MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common
(already tested by existing mcjit tests now that it is used).

ca305491f6 Sort the #include lines for the include/... tree with the script.
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

b850da774b This patch adds new functions to the SectionRef and ObjectFile interfaces to determine whether or not a section is meant to be read-only. These functions will be used by the MCJIT RuntimeDyld to give hints to the memory manager during the object loading process in a future patch.

6f8cc37074 Remove 'static' from inline functions defined in header files.
There is a pretty staggering amount of this in LLVM's header files, this
is not all of the instances I'm afraid. These include all of the
functions that (in my build) are used by a non-static inline (or
external) function. Specifically, these issues were caught by the new
'-Winternal-linkage-in-inline' warning.

I'll try to just clean up the remainder of the clearly redundant "static
inline" cases on functions (not methods!) defined within headers if
I can do so in a reliable way.

There were even several cases of a missing 'inline' altogether, or my
personal favorite "static bool inline". Go figure. ;]

6e9bcca355 This patch improves the MCJIT runtime dynamic loader by adding new handling
of zero-initialized sections, virtual sections and common symbols
and preventing the loading of sections which are not required for
execution such as debug information.

e9705e2949 [Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ST_Undefined. Implement these completely for ELF.
Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type
is unknown, not that the symbol is undefined. (For that, use ST_Undefined).

ff2a79674c Expose the ELFObjectFile class directly in the Object/ELF.h header, similarly
to what's done for MachO and COFF. This allows advanced uses of the class to
be implemented outside the Object library. In particular, the DyldELFObject
subclass is now moved into its logical home - ExecutionEngine/RuntimeDyld.

This patch was reviewed by Michael Spencer.

d2042f3698 Basic runtime dynamic loading capabilities added to ELFObjectFile, implemented
in a subclass named DyldELFObject. This class supports rebasing the object file
it represents by re-mapping section addresses to the actual memory addresses
the object was placed in. This is required for MC-JIT implementation on ELF with
debugging support.

Patch reviewed on llvm-commits.

Developed together with Ashok Thirumurthi and Andrew Kaylor.

69d98376b9 Add support for the notion of "hidden" relocations. On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves.
I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden.

Some of these can be true at the same time and there are a lot to add,
so this should be turned into a bitfield. Some of the other accessors

- Add enum SymbolType and function getSymbolType()
- Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions.
- Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address.
- Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.
