A phi node operand or an instruction operand could be a constant expression that
can trap (division). Check that we don't vectorize such cases.

to determine if a move function is the std::move function. This allows functions
like std::__1::move to also be treated a the move function.

This missing parameter was causing bin/llvm-lit to run the unittests
from my primary build directory instead of my self-hosting build
directory because llvm-config was on my PATH.
This more closely matches what 'make check' will pass to lit.py.

This completes the cleanup/refactoring of DataLayout on the clang side. Next
is figuring out the differences between the llvm and clang produced strings

The patch adds a new LLVMContext::diagnose that can be used to communicate to
the front-end, if any, that something of interest happened.
The diagnostics are supported by a new abstraction, the DiagnosticInfo class.
The base class contains the following information:
- The kind of the report: What this is about.
- The severity of the report: How bad this is.
This patch also adds 2 classes:
- DiagnosticInfoInlineAsm: For inline asm reporting. Basically, this diagnostic
will be used to switch to the new diagnostic API for LLVMContext::emitError.
- DiagnosticStackSize: For stack size reporting. Comes as a replacement of the
hard coded warning in PEI.
This patch also features dynamic diagnostic identifiers. In other words plugins
can use this infrastructure for their own diagnostics (for more details, see
getNextAvailablePluginDiagnosticKind).
This patch introduces a new DiagnosticHandlerTy and a new DiagnosticContext in
the LLVMContext that should be set by the front-end to be able to map these
diagnostics in its own system.

of objc_bridge_related attribute; eliminate
unnecessary diagnostics which is issued elsewhere,
fixit now produces a valid AST tree per convention.
This results in some simplification in handling of
this attribute as well. // rdar://15499111

Also updated tests.

that it coalesces normal copies.
Without this, MachineCSE is powerless to handle redundant operations
with truncated source operands.
This required fixing the 2-addr pass to handle tied subregisters. It
isn't clear what combinations of subregisters can legally be tied, but
the simple case of truncated source operands is now safely handled:
%vreg11<def> = COPY %vreg1:sub_32bit; GR32:%vreg11 GR64:%vreg1
%vreg12<def> = COPY %vreg2:sub_32bit; GR32:%vreg12 GR64:%vreg2
%vreg13<def,tied1> = ADD32rr %vreg11<tied0>, %vreg12<kill>, %EFLAGS<imp-def>

This reverts commit 2b43f500cfea10a8c59c986dcfc24fd08eecc77d.
This was accidentally committed because I failed to notice my client
wasn't clean prior to submitting a fix for a crasher.

CXXScopeSpec when necessary while performing typo correction. This fixes
the crash reported in PR18213 (the problem existed since r185487, and
r193020 made it easier to hit).

This was manifesting as an LLVM_ASSUME_ALIGNED() failure in an ELF debug
info test when building LLVM with clang in the Microsoft C++ ABI.
