Remat has been stable for years, and it isn't done by
LiveIntervalAnalysis any longer. (See LiveRangeEdit).

dead instructions (this isn't very useful in practice but is convenient for
analysing some testcase I am working on).  No need for WeakVH any more: use
an AssertingVH instead.

[Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

We will use the cuda library for the upcoming automatic GPGPU code generation.

Zap the /Za compiler switch from MSVC projects, the option is considered harmful even by Microsoft people and clang won't build using the MSVC 2012 RC if not removed.

Only 1 minor code change was necessary: can't use cdecl as variable name anymore.

Fix a place in GDBRemoteCommunicationClient::SendContinuePacketAndWaitForReply where we weren't taking
m_interrupt_sent into account.  Also don't reset m_interrupt_sent in SendInterrupt but do so in SendPacketAndWaitForResponse
when we know we've handled the interrupt.
Fix a code path through ProcessGDBRemote::DoDestroy where we were tearing down the debug session but
not setting the exit status.

Make sure that when if we are going to Halt while the process is in the middle of HandlePrivateEvent we
wait till that is done.  We need a stronger way to do this, but in practice this works and using some locking
strategy is harder because Halt & HandlePrivateEvent generally happen on different threads.

The output of 'register read' should be prettier.
Modify RegisterValue::Dump() to take an additional parameter:

    uint32_t reg_name_right_align_at

which defaults to 0 (i.e., no alignment at all).  Update the 'register read' command impl to pass 8
as the alignment to RegisterValue::Dump() method.  If more sophisticated scheme is desired, we will
need to introduce an additional command option to 'register read' later on.

Soon we'll be making LiveIntervalUnions for register units as well.

This was the only place using the RepReg member, so just remove it.
