This is needed by TestCases/Posix/coverage-direct.cc
The problem is that the test does:
mkdir <dir>
cd <dir>
cd ..
rm -rf <dir>
<more commands>
the current directory currently looks like "/.../<dir>/../" which
doesn't exist when dir is deleted.
at some point we should probably switch to using the os current
directory (specially if we want to add subshell), but this is a small
incremental improvement.

This is another step towards implementing register classes with
parametrized register/spill sizes and value types.
This is an updated version of r298652. The difference is that MCRegister-
Class still contains register size, available as getPhysRegSize(). The
old function getSize was retained as a temporary measure to avoid build
breakage for out-of-tree targets.

Summary:
This class is a list of AttributeSetNodes corresponding the function
prototype of a call or function declaration. This class used to be
called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is
typically accessed by parameter and return value index, so
"AttributeList" seems like a more intuitive name.
Rename AttributeSetImpl to AttributeListImpl to follow suit.
It's useful to rename this class so that we can rename AttributeSetNode
to AttributeSet later. AttributeSet is the set of attributes that apply
to a single function, argument, or return value.

These are needed due to some obscure rules in the standard
about how std::vector selects between copy and move
constructors, which can cause a conforming implementation
to attempt to select the copy constructor of RuleMatcher,
which will fail since std::unique_ptr<> isn't copyable.
llvm-svn: 298294
Summary:
Prepare the way for nested instruction matching support by having actions
like CopyRenderer look up operands in the RuleMatcher rather than a
specific InstructionMatcher. This allows actions to reference any operand
from any matched instruction.
It works by checking the 'shape' of the match and capturing
each matched instruction to a local variable. If the shape is wrong
(not enough operands, leaf nodes where non-leafs are expected, etc.), then
the rule exits early without checking the predicates. Once we've captured
the instructions, we then test the predicates as before (except using the
local variables). If the match is successful, then we render the new
instruction as before using the local variables.
It's not noticable in this patch but by the time we support multiple
instruction matching, this patch will also cause a significant improvement
to readability of the emitted code since
MRI.getVRegDef(I->getOperand(0).getReg()) will simply be MI1 after
emitCxxCaptureStmts().
This isn't quite NFC because I've also fixed a bug that I'm surprised we
haven't encountered yet. It now checks there are at least the expected
number of operands before accessing them with getOperand().

Currently we don't enforce that ISD::ANY_EXTEND, ZERO_EXTEND, SIGN_EXTEND, TRUNC, FP_ROUND, FP_EXTEND have the same number of elements(including scalar) between their input and output. Though we have them documented as such. Up until a few months ago x86 created nodes that violated this rule. That's all been fixed now, and we should enforce the rule going forward.
In order to do this we need to allow SDTCisSameNumEltsAs to support scalar types and not enforce being a vector. If one type is scalar we will force the other type to also be scalar.

There were some issues in the implementation of enumerate()
preventing it from being used in various contexts. These were
all related to the fact that it did not supporter llvm's
iterator_facade_base class. So this patch adds support for that

will evaluate an entire range and store the results in a
vector.

If `--enable-var-scope` is in effect, variables with names that
start with `$` are considered to be global. All other variables are
local. All local variables get undefined at the beginning of each
CHECK-LABEL block. Global variables are not affected by CHECK-LABEL.
This makes it easier to ensure that individual tests are not affected
by variables set in preceding tests.

Thanks to Ahmed Bougacha for finding a reasonable way to avoid the layering issue and providing the version of this patch without that problem.
The problem with the previous commit appears to have been that TableGen was including CodeGen/LowLevelType.h instead of Support/LowLevelTypeImpl.h.
