Chandler Carruth 802d755533 Sort includes for all of the .h files under the 'lib' tree. These were 
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]

Eric Christopher 7370b55262 Rewrite DIContext interface to take an object. Update all callers.

Alexey Samsonov 9cb13d59b7 Fixup for r167558: Store raw pointer (instead of reference) to RelocMap in DIContext. This is needed to prevent crashes because of dangling reference if the clients don't provide RelocMap to DIContext constructor.

Eric Christopher 7c678de861 Add a relocation visitor to lib object. This works via caching relocated 
values in a map that can be passed to consumers. Add a testcase that
ensures this works for llvm-dwarfdump.

Alexey Samsonov c942e6b781 Add support for fetching inlining context (stack of source code locations) 
by instruction address from DWARF.

Add --inlining flag to llvm-dwarfdump to demonstrate and test this functionality,
so that "llvm-dwarfdump --inlining --address=0x..." now works much like
"addr2line -i 0x...", provided that the binary has debug info
(Clang's -gline-tables-only *is* enough).

Alexey Samsonov 45be793e3a Refactor fetching file/line info from DWARFContext to simplify the 
code and allow better code reuse. Make the code a bit more conforming
to LLVM code style.
No functionality change.

Alexey Samsonov 034e57a297 Add basic support for .debug_ranges section to LLVM's DebugInfo library. 
This section (introduced in DWARF-3) is used to define instruction address
ranges for functions that are not contiguous and can't be described
by low_pc/high_pc attributes (this is the usual case for inlined subroutines).
The patch is the first step to support fetching complete inlining info from DWARF.

Alexey Samsonov f4462fa3ca This patch extends the libLLVMDebugInfo which contains a minimalistic DWARF parser: 
1) DIContext is now able to return function name for a given instruction address (besides file/line info).
2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag).
3) test case that checks the basic functionality of llvm-dwarfdump added

Benjamin Kramer 679e1752f8 DWARF: Remove accessors that parse the whole line table section in one go, this can't possibly work. 
The address size is specified by the compile unit associated with a line table, there is no global address size.

Benjamin Kramer a6002fd920 DWARF: Port support for parsing .debug_aranges section from LLDB and wire it up to llvm-dwarfdump. 
This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is
not available will be ported soon.

Benjamin Kramer aa2f78f5e6 Sketch out a DWARF parser. 
This introduces a new library to LLVM: libDebugInfo. It will provide debug information
parsing to LLVM. Much of the design and some of the code is taken from the LLDB project.

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.
