Part of the project to eliminate special handling for triples in lit
expressions.

Jake Egan 9feb461375 Generalize DWARF tests that expect DW_FORM_strp
The modified tests were failing on AIX because DWARF on AIX uses inline strings by default, but the tests check for `DW_FORM_strp`.

This patch removes `DW_FORM_strp` so both forms will pass the check.

Rainer Orth 7af4bbb643 [test] XFAIL two tests with inlining debug info issues on Sparc
Currently only two test failures remain on Sparc, both
`sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`:

  LLVM :: DebugInfo/Generic/debug-label-inline.ll
  LLVM :: Linker/subprogram-linkonce-weak.ll

They seem related in that debug info isn't generated for instruction
bundles (like `retl+add` in the delay slot).

I've filed separate bugs for both files (Bug 47129 and 47131), though it's
probably the same issue.

This patch `XFAIL`s the tests.

Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.

Petar Jovanovic e2877ad3b9 [DebugInfo] Fix debug information label tests
Remove the space in the asm check so that the expression is more general
and can also capture MIPS labels which can be surrounded by braces, e.g.:

.4byte        ($tmp1)                 # DW_AT_low_pc

Also change optimization level to O0 because the DW_TAG_label does not
appear on MIPS when -O2 is used.

Hsiangkai Wang 2532ac880a [DebugInfo] Generate DWARF debug information for labels. (Fix leak problems)
There are two forms for label debug information in DWARF format.

1. Labels in a non-inlined function:

DW_TAG_label
  DW_AT_name
  DW_AT_decl_file
  DW_AT_decl_line
  DW_AT_low_pc

2. Labels in an inlined function:

DW_TAG_label
  DW_AT_abstract_origin
  DW_AT_low_pc

We will collect label information from DBG_LABEL. Before every DBG_LABEL,
we will generate a temporary symbol to denote the location of the label.
The symbol could be used to get DW_AT_low_pc afterwards. So, we create a
mapping between 'inlined label' and DBG_LABEL MachineInstr in DebugHandlerBase.
The DBG_LABEL in the mapping is used to query the symbol before it.

The AbstractLabels in DwarfCompileUnit is used to process labels in inlined
functions.

We also keep a mapping between scope and labels in DwarfFile to help to
generate correct tree structure of DIEs.

It also generates label debug information under global isel.
