Added a regex that can be specified to avoid showing contents on types that match. Also split things up a bit so this can be run as a stand alone script or in lldb.

Although in reality the symbol table in ELF resides in a section, the
standard requires that there be no more than one SHT_SYMTAB. To enforce
this constraint, it is cleaner to group all the symbols under a
top-level `Symbols` key on the object file.

The improperly aligned section content in the output was causing
buildbot failures. This should fix them.

Incidentally, this results in a simpler and more robust API for
ContiguousBlobAccumulator.

We have no targets on trunk that bundle before regalloc. However, we
have been advertising regalloc as bundle safe for use with out-of-tree
targets. We need to at least contain the parts of the code that are
still unsafe.

Now, the way SWIG wrappers call into Python is through a utility PyCallable object, which overloads operator () to look like a normal function call
Plus, using the SBTypeToSWIGWrapper() family of functions, we can call python functions transparently as if they were plain C functions
Using this new technique should make adding new Python call points easier and quicker

The PyCallable is a generally useful facility, and we might want to consider moving it to a separate layer where other parts of LLDB can use it

It wouldn't really test anything that doesn't already have a more
targeted test:
`yaml2obj-elf-section-basic.yaml`:
  Already tests that section content is correctly passed though.
`yaml2obj-elf-symbol-basic.yaml` (this file):
  Tests that the st_value and st_size attributes of `main` are set
  correctly.
Between those two tests, disassembling the file doesn't really add
anything, so just remove mention of disassembling the file.

This reverts commit r184602. In an upcoming commit, I will just remove
the disassembler part of the test; it was mostly just a "nifty" thing
marking a milestone but it doesn't test anything that isn't tested
elsewhere.

Empty structs are ignored for parameter passing purposes, but va_arg was
incrementing the pointer anyway which could lead to va_list getting out of
sync.

A FastISel optimization was causing us to emit no information for such
parameters & when they go missing we end up emitting a different
function type. By avoiding that shortcut we not only get types correct
(very important) but also location information (handy) - even if it's
only live at the start of a function & may be clobbered later.

According to the Itanium ABI (3.1.1), types with non-trivial copy constructors
passed by value should be passed indirectly, with the caller creating a
temporary.

We got this mostly correct, but forgot that empty structs can have non-trivial
constructors too and passed them incorrectly. This simply reverses the order of
the check.

that have been run through the 'C' pre-processor.

The implementation of SrcMgr.FindLineNumber() is slow but OK if
it uses its cache when called multiple times with an SMLoc that is
forward of the previous call.

In the case of generating dwarf for assembly source files that have
been run through the 'C' pre-processor we need to calculate the
logical line number based on the last parsed cpp hash file line
comment.  And the current code calls SrcMgr.FindLineNumber()
twice to do this causing its cache not to work and results in very
slow compile times:

% time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g
672.542u 0.299s 11:13.15 99.9%	0+0k 0+2io 2106pf+0w

So we save the info from the last parsed cpp hash file line comment
to avoid making the second call to SrcMgr.FindLineNumber() most times
and end up with compile times like:

% time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g
3.404u 0.104s 0:03.80 92.1%	0+0k 0+3io 2105pf+0w
