Add a "debugger tuning" concept that allows us to fine-tune how we emit debug info, according to the preferences of the different debuggers used on various targets. Darwin and FreeBSD default to tuning for LLDB; PS4 defaults to tuning for the SCE (Sony Computer Entertainment) debugger. All others default to GDB.

; Verify target-based defaults for "debugger tuning," and the ability to
; override defaults.
; We use existence of the debug_pubnames section to distinguish the GDB case,
; and the apple_names section to distinguish the LLDB case. SCE has neither.
; Verify defaults for various targets.

Turn off lldb debug tuning by default for FreeBSD Summary: In rL242338, debugger tuning was introduced, and the tuning for FreeBSD was set to lldb by default. However, for the foreseeable future we still need to default to gdb tuning, since lldb is not ready for all of FreeBSD's architectures, and some system tools (like objcopy, etc) have not yet been adapted to cope with the lldb tuned format, which has .apple sections. Therefore, let FreeBSD use gdb by default for now. Reviewers: emaste, probinson Subscribers: llvm-commits, emaste Differential Revision: http://reviews.llvm.org/D15966 llvm-svn: 257103

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.
