DISubrange supports unsigned lower/upper array bounds, so let's not fake it in the end while emitting DWARF. If a FE needs to encode signed lower/upper array bounds then we need to extend DISubrange or ad DISignedSubrange. llvm-svn: 144937

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

Implement DW_TAG_subrange_type with DW_AT_count rather than DW_AT_upper_bound This allows proper disambiguation of unbounded arrays and arrays of zero bound ("struct foo { int x[]; };" and "struct foo { int x[0]; }"). GCC instead produces an upper bound of -1 in the latter situation, but count seems tidier. This way lower_bound is provided if it's not the language default and count is provided if the count is known, otherwise it's omitted. Simple. If someone wants to look at rdar://problem/12566646 and see if this change is acceptable to that bug/fix, that might be helpful (see the empty-and-one-elem-array.ll test case which cites that radar). llvm-svn: 218726
