[libclang] Have clang_getCXXAccessSpecifier() also return the access control of a C++ declaration within its parent scope.

Suggested by Stefan Seefeld.

Static variables inside classes were not being added to the RecordDecl, now they are. This gets us closer to being able to display static variables in classes.

With this patch llvm-readobj now prints if a relocation is pcrel, its length,
if it is extern and if it is scattered.

It also refactors the code a bit to use bit fields instead of shifts and
masks all over the place.

When trying to collapse sequences of insertelement/extractelement
instructions into single shuffle instructions, there is one specific
case where the Instruction Combiner wrongly updates the resulting
Mask of shuffle indexes.

The problem is in function CollectShuffleElments.

If we have a sequence of insert/extract element instructions
like the one below:

  %tmp1 = extractelement <4 x float> %LHS, i32 0
  %tmp2 = insertelement <4 x float> %RHS, float %tmp1, i32 1
  %tmp3 = extractelement <4 x float> %RHS, i32 2
  %tmp4 = insertelement <4 x float> %tmp2, float %tmp3, i32 3

Where:
  . %RHS will have a mask of [4,5,6,7]
  . %LHS will have a mask of [0,1,2,3]

The Mask of shuffle indexes is wrongly computed to [4,1,6,7]
instead of [4,0,6,7].
When analyzing %tmp2 in order to compute the Mask for the
resulting shuffle instruction, the algorithm forgets to update
the mask index at position 1 with the index associated to the
element extracted from %LHS by instruction %tmp1.

Thanks to Reid Kleckner for catching this.

Pre- and post- hooks for linux syscalls. Not wired into anything, but exposed
through public interface.

Function declarations are now broken with the following preferences:
1) break amongst arguments.
2) break after return type.
3) break after (.
4) break before after nested name specifiers.

Options #2 or #3 are preferred over #1 only if a substantial number of
lines can be saved by that.

This will be used in clang to decide if it should create an @file or not. It
will be tested on the clang side.

The bots seem to do more line wrapping because they have longer absolute
paths.

The behavior can be overridden by setting LIT_USE_INTERNAL_SHELL=0 in
the environment.

This fixes issues with /dev/null for me and brings the test suite time
down to 30s.  =D

This required some tedious reordering to match clang's order.
Presumably these ObjC tests were generated based on llvm-gcc's output
ordering.

As packed comparisons in AVX/SSE produce all 0s or all 1s in each SIMD lane,
vector select could be simplified to AND/OR or removed if one or both values
being selected is all 0s or all 1s.

As these two instructions in AVX extension are privileged instructions for
special purpose, it's only expected to be used in inlined assembly.

This patch is revised based on patch from Victor Umansky
<victor.umansky@intel.com>. More cases are handled in X86's bool
simplification, i.e.
- SETCC_CARRY
- value is truncated to i1 with AND

As a by-product, PR5443 is also fixed.
