[ASan] Clear allocation magic value before recycling the chunk. This led to spurious crashes in LSan when it walked through reused chunks. Don't know how to create not-brittle test case for this.

llvm-svn: 184404

Summary:
When doing a reinterpret+dynamic cast from an incomplete type, the analyzer
would crash (bug #16308). This fix makes the dynamic cast evaluator ignore
incomplete types, as they can never be used in a dynamic_cast. Also adding a
regression test.

This fixes PR16370, I'll add the test case in a follow-up commit.

This change moves the functionality of undefinedSymbols that were created in
ELFTargetInfo into TargetInfo. Looks like MachO/Windows use similiar options
like in ELF for creating undefined symbols when the linker is invoked.

Address comment from Ruiu.

(No change in functionality, except moving the functionality from ELF to
TargetInfo, so that multiple architectures can use the same)

Fixes utilities/tuple/tuple.tuple/tuple.creation/tuple_cat.pass.cpp from the
libc++ testsuite.

  return false;

in a function returning a pointer. 'false' was a null pointer constant in C++98
but is not in C++11. Punch a very small hole in the initialization rules in
C++11 mode to allow this specific case in system headers.

Cleanup the output a bit by removing old print statements and also printing the number of types found.

llvm-svn: 184389

Unique types a bit more using the clang type to make sure we don't get multiple copies of the same type due to the debug info having multiple types that get uniqued.

Fix up three tests - one that was relying on abbreviation number,
another relying on a location list in this case (& testing raw asm,
changed that to use dwarfdump on the debug_info now that that's where
the location is), and another which was added in r184368 - exposing a
bug in that fix that is exposed when we emit the location inline rather
than through a location list. Fix that bug while I'm here.

[clang-lit] Added the run_long_tests param option/long_tests feature to toggle execution of long running FileCheck tests.

This will allow for longer running FileCheck based tests to be committed to
clang for use on buildbots, preventing the normal make-check cycle from
increasing in time significantly.

This is a necessary change in order to commit the end-to-end arm neon intrinsic
tests since FileCheck takes ~20 seconds to run said test due to the large amount
of neon intrinsics.

To force a test to run only when --param run_long_tests=true is passed in use
the following requires statement:

// REQUIRES: long_tests

[libclang] Make sure crash-recovery for module-building does not interfere with libclang crash-recovery.

[Support/CrashRecoveryContext] Make sure CrashRecoveryContext does not clear the thread-local "CurrentContext"
in the "parent" thread, when we are using CrashRecoveryContext::RunSafelyOnThread.

When using CrashRecoveryContext::RunSafelyOnThread, we would set a CrashRecoveryContextImpl* to a thread-local variable
for the "child" thread, but CrashRecoveryContext would erroneously clear it in the "parent" thread.

The result was that if CrashRecoveryContext::RunSafelyOnThread was called again in the "child" thread it would mess up
crash-recovery for its parent.

A test for this will be added in the clang repository.

We had been papering over a problem with location info for non-trivial
types passed by value by emitting their type as references (this caused
the debugger to interpret the location information correctly, but broke
the type of the function). r183329 corrected the type information but
lead to the debugger interpreting the pointer parameter as the value -
the debug info describing the location needed an extra dereference.

Use a new flag in DIVariable to add the extra indirection (either by
promoting an existing DW_OP_reg (parameter passed in a register) to
DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n
(parameter passed on the stack).
