Pavel Labath 418a272f4a [dotest] Avoid the need for LEVEL= makefile boilerplate
Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.

This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.

The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:
  find . \( -name Makefile -o -name '*.mk' \)  -exec sed --in-place -e '/LEVEL *:\?=/d' -e '1,2{/^$/d}' -e 's,\$(LEVEL)/,,' {} +

Thanks to Pavel for pointing this out.

Pavel Labath d214898f1f Split TestVLA into two and XFAIL one part
The part which checks whether vla_expr shows up in the variable list
does not pass on non-darwin platforms. Add the appropriate decorator.

Adrian Prantl 1db0f0ca98 Hide runtime support values such as clang's __vla_expr from frame variable
by respecting the "artificial" attribute on variables. Function
arguments that are artificial and useful to end-users are being
whitelisted by the language runtime.

Adrian Prantl eca07c592a Fix (and improve) the support for C99 variable length array types
Clang recently improved its DWARF support for C VLA types. The DWARF
now looks like this:

0x00000051:         DW_TAG_variable [4]
                     DW_AT_location( fbreg -32 )
                     DW_AT_name( "__vla_expr" )
                     DW_AT_type( {0x000000d3} ( long unsigned int ) )
                     DW_AT_artificial( true )
...
0x000000da:     DW_TAG_array_type [10] *
                 DW_AT_type( {0x000000cc} ( int ) )

0x000000df:         DW_TAG_subrange_type [11]
                     DW_AT_type( {0x000000e9} ( __ARRAY_SIZE_TYPE__ ) )
                     DW_AT_count( {0x00000051} )

Without this patch LLDB will naively interpret the DIE offset 0x51 as
the static size of the array, which is clearly wrong.  This patch
extends ValueObject::GetNumChildren to query the dynamic properties of
incomplete array types.

See the testcase for an example:

   4   int foo(int a) {
   5   	     int vla[a];
   6   	       for (int i = 0; i < a; ++i)
   7   	           vla[i] = i;
   8
-> 9            pause(); // break here
   10  		return vla[a-1];
   11   }

(lldb) fr v vla
(int []) vla = ([0] = 0, [1] = 1, [2] = 2, [3] = 3)
(lldb) quit
