5758d6af22 Always use the string pool, even when it makes the .o larger. This may help 
tools that read the debug info in the .o files by making the DIE sizes more
consistent.

57c57a3260 Add a new wrapper node for a DILexicalBlock that encapsulates it and a 
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

e4127d626e Do not use named md nodes to track variables that are completely optimized. This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly.

9ce5cebde6 Fix a regression I recently introduced by removing DwarfRegNum of 
subregisters:

When a value is in a subregister, at least report the location as being
the superregister. We should extend the .td files to encode the bit
range so that we can produce a DW_OP_bit_piece.

92dc58fea6 Use .cfi_sections to put the unwind info in .debug_frame when possible. With 
this clang will use .debug_frame in, for example,
clang -g -c -m32 test.c
This matches gcc's behaviour. It looks like .debug_frame is a bit bigger
than .eh_frame, but has the big advantage of not being allocated.

8346c59e6a Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, but 
it is both inefficient and unexpected by dwarfdump. Change to
a DW_FORM_data4.

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a
relocation.

39ac307002 Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array. 
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.

93a07b464e Change CodeGen to use .loc directives. This produces a lot more readable output 
and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.

71a27d5aa6 DwarfWrite is now smart enough to drop debug value pointing to undefined register. Update this test to avoid this.
