Different object file formats support DWARF sections (COFF, ELF, MachO,
PE/COFF, WASM). COFF and PE/COFF only matched a subset. This caused some
GCC executables produced on MinGW to have issue later on when debugging.
One example is that `.debug_rnglists` was not matched, which caused
range-extraction to fail when printing a backtrace.

This unifies the parsing of section names in
`ObjectFile::GetDWARFSectionTypeFromName`, so all file formats can use
the same naming convention. Since the prefixes are different,
`GetDWARFSectionTypeFromName` only matches the suffixes (i.e. `.debug_`
needs to be stripped before).

I added two tests to ensure the sections are correctly identified on
Windows executables.

If we're not touching them, we don't need to do anything special to pass
them along -- with one important caveat: due to how cmake arguments
work, the implicitly passed arguments need to be specified before
arguments that we handle.

This isn't particularly nice, but the alternative is enumerating all
arguments that can be used by llvm_add_library and the macros it calls
(it also relies on implicit passing of some arguments to
llvm_process_sources).

Lots of code around LLDB was directly accessing the target's section
load list. This NFC patch makes the section load list private so the
Target class can access it, but everyone else now uses accessor
functions. This allows us to control the resolving of addresses and will
allow for functionality in LLDB which can lazily resolve addresses in
JIT plug-ins with a future patch.

Note that PointerUnion::{is,get} have been soft deprecated in
PointerUnion.h:

  // FIXME: Replace the uses of is(), get() and dyn_cast() with
  //        isa<T>, cast<T> and the llvm::dyn_cast<T>

Compared to the python version, this also does type checking and error
handling, so it's slightly longer, however, it's still comfortably
under 500 lines.

Add support for type summaries embedded into the binary.

These embedded summaries will typically be generated by Swift macros,
but can also be generated by any other means.

buildbot fixes.

Allow LLDB to parse the dynamic symbol table from an ELF file or memory
image in an ELF file that has no section headers. This patch uses the
ability to parse the PT_DYNAMIC segment and find the DT_SYMTAB,
DT_SYMENT, DT_HASH or DT_GNU_HASH to find and parse the dynamic symbol
table if the section headers are not present. It also adds a helper
function to read data from a .dynamic key/value pair entry correctly
from the file or from memory.

This reverts commit a7b2e73bcaa91255a20f1f2e692bec9eb6c17022.
