* Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile.
* Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable.
* Implement this new interface completely for ELF, leave stubs for COFF and MachO.
* Add 'llvm-readobj' tool for dumping ObjectFile information.

This allows the function to be inlined, and makes it suitable for use in
getInstructionIndex().

Also provide a const version. C++ is great for touch typing practice.

Shrinks BasicAliasAnalysis.o from 106k to 56k on i386.

Convert the thread plans over from using the stack count to do their logic to using StackID's.  This
should be more efficient.

While we're at it - don't copy vreg implicit operands while rematerializing.

- The search bounds are constant, in the worst case (ARM target) it will scan over 30 uint16_ts.
- This method isn't very hot, I had problems finding a testcase where it's called more than a dozen of times (no perf impact).

So with darwin's otool(1) an x86_64 hello world .o file will print:

Fixes PR10606.

I'm not sure if this is the best way to go about it, but
I locally enabled this code path without the msext conditional,
and all tests pass, except for test/Preprocessor/cxx_oper_keyword.cpp
which explicitly checks that operator keywords can't be redefined.

I also parsed chromium/win with a clang with and without this patch.
It introduced no new errors, but removes 43 existing errors.

Doesn't help ARM with its massive register set, but halves the size on x86 and all other targets.

Incremental check in to calculate the offsets of registers correctly.  Registers can be primordial or composite,
for example, r0-r12 are primordial, s0-s31 are primordial, while q0 is composite consisting of (s0, s1, s2, s3).
Modify q0-q8 to be composed of the primordial s0-s31 registers.

Instead of nested switch statements, use a lookup table. On ARM, this replaces
a 23k (x86_64 release build) function with a 16k table. Its not unlikely to
be faster, as well.

Unfortunately, the default TargetLibraryInfo constructor assumes all library

Use the correct (computed by the unwinder) CallFrameAddress as the CFA for Frame 0 rather than using the stack pointer which is not constant over the life of the frame.
