A bunch of fixes to argument passing and va_arg on Darwin x86-32 for structures containing an SSE vector.

[asan] workaround for reg alloc bug 11395: don't instrument functions with large chunks of inline assembler

llvm-svn: 144961

Simplify code for returning a struct for Darwin x86-32 ABI.  Use a better type for a function returning a struct containing only a pointer.  Handle the edge case of a struct containing only a float or double plus some dead padding instead of asserting.

-For indexDeclaration, also pass the declaration attributes as an array of cursors.
-Rename CXIndexOpt_OneRefPerFile -> CXIndexOpt_SuppressRedundantRefs, and only pass
  a reference if a declaration/definition does not exist in the file.

DISubrange supports unsigned lower/upper array bounds, so let's not fake it in the end while emitting DWARF. If a FE needs to encode signed lower/upper array bounds then we need to extend DISubrange or ad DISignedSubrange.

quick fix: remove GlobalVariable::GlobalVariable mistakenly commited at r144933. For some reason this compiles on linux

The right way to check for a binary operation is
cast<BinaryOperator>. The original check: cast<Instruction> &&
numOperands() == 2 would match phi "instructions", leading to an
infinite loop in extreme corner case: a useless phi with operands
[self, constant] that prior optimization passes failed to remove,
being used in the loop by another useless phi, in turn being used by an
lshr or udiv.

Fixes PR11350: runaway iteration assertion.

fall back to explicit list of allowed linkages when instrumenting globals in asan; add a test check that asan does not touch linkonce_odr

When the solver and SValBuilder cannot reason about symbolic expressions (ex: (x+1)*y ), the analyzer conjures a new symbol with no ties to the past. This helps it to recover some path-sensitivity. However, this breaks the taint propagation.

With this commit, we are going to construct the expression even if we cannot reason about it later on if an operand is tainted.

Also added some comments and asserts.

Fix bug in RefCountedBase/RefCountedBaseVPTR where the reference count was accidentally copied as part of the copy constructor.  This could result in objects getting leaked because there reference count was too high.

llvm-svn: 144931

Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object.  I discovered that llvm::RefCountedBase<T> has
a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked.  When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive.  By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.

As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.

This commit doesn't fix the CompilerInvocation leak itself.  That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.

Simplify crash cleanup logic in ASTUnit::LoadFromCommandLine() by zeroing out two IntrusiveRefCnt pointers after we have assigned their respective values into fields of ASTUnit.

Use this option with care as you would need to build the inferior(s) by hand
and build the executable(s) with the correct name(s).  This option can be used
with '-# n' to stress test certain test cases for n number of times.

We disable Polly by default and add a new option '-polly' that enables Polly.
This allows us to create an the alias

$ alias clang clang -Xclang -load -Xclang LLVMPolly.so

which loads Polly always into clang. It can now be enabled by running:

$ clang -O3 -mllvm -polly file.c

To enable it by default an alias pollycc can be create

$ alias pollycc clang -O3 -mllvm -polly
