Remove unneeded member in CommentSema, add a test for the XML schema (the
schema already allowed multiple paragraphs in <ResultDiscussion>, but there
were no tests for that), fix HTML generation (it is not allowed to have <p>
inside <dl>).

Rewrote the SLP-vectorization as a whole-function vectorization pass. It is now able to vectorize chains across multiple basic blocks.
It still does not vectorize PHIs, but this should be easy to do now that we scan the entire function.
I removed the support for extracting values from trees.
We are now able to vectorize more programs, but there are some serious regressions in many workloads (such as flops-6 and mandel-2).

There are fundamentally two different things that were getting conflated
here.
1) A bi-arch GCC toolchain install. This is not a full blown cross
compiler, but it supports targetting both 32-bit and 64-bit variants
of the same architecture using multilib OS installs and runtimes.
2) A "multiarch" Debian OS/runtime layout that lays out the libraries,
headers, etc as-if there were going to be a full blown cross compiler
even when in reality it is just a bi-arch GCC targeting two variants.
Also, these tend to use oddly "canonicalized" triples without the
vendor in them unlike the typical cross compiler runtime library
search that vanilla GCC cross compilers perform.
Now, when we mean the bi-arch nature of GCC accomplished with just
a suffix or tweak to the GCC paths, we say 'Biarch' or something
related. When we mean the Debian layout of includes and libraries, we
say multiarch or reference the multiarch triple.
In the process of reading and often renaming stuff in all these places,
also reformat with clang-format. No functionality change should be going
on here, this is just tidying up.

The problem with r183462 was that we assumed that a diagnostic id of
zero would be silent.
This small correction to CheckDerivedToBaseConversion changes it's
behavior to omit the diagnostic when given a diagnostic id of zero.
This fix passes the test case added in r184402.

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.

This fixes false positives by allowing us to know that a loop is always entered if
the collection count method returns a positive value and vice versa.

Add the back edge info by creating a basic block, marked as loop target. This is
consistent with how other loops are processed, but was omitted from
VisitObjCForCollectionStmt.

Set your env variable LLDB_TEST_ARGUMENTS to one or more options to be passed to the lldb test suite and those will be picked automatically
No more fighting about whether the progress bar is good or bad :-)

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.
