The field "pid" in ReportThread is used to store the OS-provided thread ID (pthread_self or gettid). The name "pid" suggests it's a process ID, which it isn't. Let's rename it.

This patch adds a new TSan report type, ReportTypeMutexInvalidAccess, which is triggered when pthread_mutex_lock or pthread_mutex_unlock returns EINVAL (this means the mutex is invalid, uninitialized or already destroyed).

Return a linked list of AddressInfo objects, instead of using an array of
these objects as an output parameter. This simplifies the code in callers
of this function (especially TSan).
Fix a few memory leaks from internal allocator, when the returned
AddressInfo objects were not properly cleared.
llvm-svn: 223145
# Make DataInfo (describing a global) a member of ReportLocation
to avoid unnecessary copies and allocations.
# Introduce a constructor and a factory method, so that
all structure users don't have to go to internal allocator directly.
# Remove unused fields (file/line).
No functionality change.

AddressInfo contains the results of symbolization. Store this object
directly in the symbolized stack, instead of copying data around and
making unnecessary memory allocations.
No functionality change.

The refactoring makes suppressions more flexible
and allow to suppress based on arbitrary number of stacks.
In particular it fixes:

"Make it possible to suppress deadlock reports by any stack (not just first)"

Status:
The tool is known to work on large real-life applications, but still has quite a few rough edges.
Nothing is guaranteed yet.
The tool works on x86_64 Linux.
Support for 64-bit MacOS 10.7+ is planned for late 2012.
Support for 32-bit OSes is doable, but problematic and not yet planed.
Further commits coming:
- tests
- makefiles
- documentation
- clang driver patch
