Clarify when we can avoid creating names for temp symbols.
Some temporary symbols are created by MC itself. These symbols are never used
for lookup and are never included in the object symbol table, so we can
avoid creating a name for them.
Other temporaries are created by CodeGen or by the user by explicitly asking
for a name starting with .L (or L on MachO).
These temporaries behave like regular symbols, we just try to avoid including
them in the object symbol table, but sometimes they end up there:
const char *foo() {
return "abc" + 3;
}
will have a relocation pointing to a .L symbol.
It just so happens that almost all MC created temporary has the AlwaysAddSuffix
option and CodeGen/user created ones don't.
One interesting future optimization would be to use unnamed symbols for
all temporaries, but that would require use an st_name of 0 or
having the object writer create the names if a symbol does end up in the
symbol table.
No testcase since this just avoid creating a few extra names for MC created
temporaries.

[RewriteStatepointsForGC] Strip deref info after rewriting.
Summary:
Once a gc.statepoint has been rewritten to relocate live references, the
SSA values represent physical pointers instead of logical references.
Logical dereferencability does not imply physical dereferencability and
after RewriteStatepointsForGC has run any attributes that imply
dereferencability of the logical references need to be stripped.
This current approach is conservative, and can be made more precise
later if needed. For starters, we need to strip dereferencable
attributes only from pointers that live in the GC address space.

LLVM's MI level notion of invariant_load is different from LLVM's IR

IR notion of invariant_load only guarantees that all *non-faulting*
invariant loads result in the same value. The MI notion of invariant
load guarantees that the load can be legally moved to any location
within its containing function. The MI notion of invariant_load is
stronger than the IR notion of invariant_load -- an MI invariant_load is
an IR invariant_load + a guarantee that the location being loaded from
is dereferenceable throughout the function's lifetime.

[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.

This test is going to get a lot bigger soon and it will become essentially unreadable if the current formatting is kept.
I've also made the comments more useful and accurate, and I've restricted the RUN lines to under 80 columns.

non-adjacent registers, on thumb2 this is not necessary.
Ideally on thumb2 we shouldn't match for ldrd/strd pre-regalloc anymore

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.
