[x86-64 ABI] Fix for PR23082: an assertion failure when passing/returning a wrapper union in a full YMM register.
This patch fixes an assertion failure in method
'X86_64ABIInfo::GetByteVectorType'.
Method 'GetByteVectorType' (in TargetInfo.cpp) is responsible
for mapping a QualType 'Ty' (for an argument or return value) to an LLVM IR
type that, according to the ABI, must be passed in a XMM/YMM vector register.
When selecting the IR vector type, method 'GetByteVectorType' always tries to
choose the "best" IR vector type for the 'Ty' in input. In particular, if Ty
is a wrapper structure, it keeps unwrapping it until it finds a vector type VTy.
That VTy is the "preferred IR type".
However, function 'isSingleElementStructure' (used to unwrap structures) does
not know how to look through union types. So, before this patch, if Ty was in
a nest of wrapper structures with at least two union types, we would have
triggered an assertion failure (added at revision 230971).
With this patch, if method 'GetByteVectorType' fails to find the preferred
vector type, we just return a valid (although potentially 'less friendly')
vector type based on the type size. So, rather than asserting on an 'unexpected'
'Ty' in input, we conservatively return vector type <2 x double> if Ty is 16
bytes, or <4 x double> if Ty is 32 bytes.

ARM: Thumb2 LDRD/STRD supports independent input/output regs
The existing code would unnecessarily break LDRD/STRD apart with
non-adjacent registers, on thumb2 this is not necessary.
Ideally on thumb2 we shouldn't match for ldrd/strd pre-regalloc anymore
as there is not reason to set register hints anymore, changing that is
something for a future patch however.

Fix a race condition where 2 threads might try to call Process::SetExitStatus() at the same time.
The problem was the mutex was only protecting the setting of m_exit_string and m_exit_string, but this function relies on the m_private_state being set to eStateExited in order to prevent more than 1 client setting the exit status. We want to only allow the first caller to succeed.
On MacOSX we have a thread that reaps the process we are debugging, and we also have a thread that monitors the debugserver process. When a process exists, the ProcessGDBRemote::AsyncThread() would set the exit status to the correct value and then another thread would reap the debugserver process and they would often both end up in Process::SetExitStatus() at the same time. With the mutex at the top we allow all variables to be set and the m_private_state to be set to eStateExited _before_ the other thread (debugserver reaped) can try to set th exist status to -1 and "lost connection to debugserver" being set as the exit status.
This was probably an issue for lldb-server as well and could very well cleanup some tests that might have been expecting a specific exit status from the process being debugged.

Move the name pointer out of Value into a map that lives on the
LLVMContext. Production builds of clang do not set names on most
Value's, so this is wasted space on almost all subclasses of Value.
This reduces the size of all Value subclasses by 8 bytes on 64 bit
hosts.
The one tricky part of this change is averting compile time regression
by keeping Value::hasName() fast. This required stealing bits out of
NumOperands.
With this change, peak memory usage on verify-uselistorder-nodbg.lto.bc
is decreased by approximately 2.3% (~3MB absolute on my machine).

COFF: Support import-by-ordinal DLL imports.
Symbols exported by DLLs can be imported not by name but by
small number or ordinal. Usually, symbols have both ordinals
and names, and in that case ordinals are called "hints" and

However, symbols can have only ordinals. They are called
import-by-ordinal symbols. You need to manage ordinals by hand
so that they will never change if you choose to use the feature.
But it's supposed to make dynamic linking faster because
it needs no string comparison. Not sure if that claim still
stands in year 2015, though. Anyways, the feature exists,
