We already support GR64 <-> VR128 copies. All of these copies break
partial register dependencies by zeroing the high part of the target
register.

Add eArgTypeWatchpointID and eArgTypeWatchpointIDRange to the CommandArgumentType enums and
modify the signature of CommandObject::AddIDsArgumentData() from:
AddIDsArgumentData(CommandArgumentEntry &arg)
to:
AddIDsArgumentData(CommandArgumentEntry &arg, CommandArgumentType ID, CommandArgumentType IDRange)
to accommodate.

The solution is to create a new ParseScope(Scope::TemplateParamScope) for each template scope that we want to reenter. (from the outmost to the innermost scope)
This fixes some errors when parsing MFC code with clang.

This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there.
The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs.
Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend.
I tried to match GCC's behavior as close as possible
Fixes PR8971.

Sometimes register class constraints are trivial, like GR32->GR32_NOSP,
or GPR->rGPR. Teach InstrEmitter to simply constrain the virtual
register instead of emitting a copy in these cases.
Normally, these copies are handled by the coalescer. This saves some
coalescer work.

The function will refuse to use a register class with fewer registers
than MinNumRegs. This can be used by clients to avoid accidentally
increase register pressure too much.
The default value of MinNumRegs=0 doesn't affect how constrainRegClass()
works.

It's not valid to remove filters from landingpad instructions, even if we catch
the type. The metadata won't be set up correctly.
Testcase is projects/llvm-test/SingleSource/UnitTests/EH/filter-2.cpp.

generation when we're dealing with an implicitly-defined copy or move
constructor. And, actually set the implicitly-defined bit for
implicitly-defined constructors and destructors. Should fix self-host.

addition the defined OLD_EXC_SYSTEM was not tested with this version.

infrastructure. As this makes the demo no longer a demo, and especially not a
demo on how to use the llvm exception mechanism, this hack will shortly be
changed to use the new 3.0 exception infrastructure. However for the time being
this demo is an example on how to use the AutoUpgrade
UpgradeExceptionHandling(...) function on < 3.0 exception handling code.
