[Driver] Force llvm to install its handlers before lldb's

Install llvm's signal handlers up front to prevent lldb's handlers from being
ignored. This is (hopefully) a stopgap workaround.

When lldb invokes an llvm API that installs signal handlers (e.g.
llvm::sys::RemoveFileOnSignal, possibly via a compiler embedded within lldb),
lldb's signal handlers are overriden if llvm is installing its handlers for the
first time.

To work around llvm's behavior, force it to install its handlers up front, and
*then* install lldb's handlers. In practice this is used to prevent lldb test
processes from exiting due to IO_ERR when SIGPIPE is received.

Note that when llvm installs its handlers, it 1) records the old handlers it
replaces and 2) re-installs the old handlers when its new handler is invoked.
That means that a signal not explicitly handled by lldb can fall back to being
handled by llvm's handler the first time it is received, and then by the
default handler the second time it is received.

ValueObject: Fix a crash related to children address type computation

Summary:
This patch fixes a crash encountered when debugging optimized code. If some
variable has been completely optimized out, but it's value is nonetheless known,
the compiler can replace it with a DWARF expression computing its value. The
evaluating these expressions results in a eValueTypeHostAddress Value object, as
it's contents are computed into an lldb buffer. However, any value that is
obtained by dereferencing pointers in this object should no longer have the
"host" address type.

Lldb had code to account for this, but it was only present in the
ValueObjectVariable class. This wasn't enough when the object being described
was a struct, as then the object holding the actual pointer was a
ValueObjectChild. This caused lldb to dereference the contained pointer in the
context of the host process and crash.

Though I am not an expert on ValueObjects, it seems to me that this children
address type logic should apply to all types of objects (and indeed, applying
applying the same logic to ValueObjectChild fixes the crash). Therefore, I move
this code to the base class, and arrange it to be run everytime the value is
updated.

The test case is a reduced and simplified version of the original debug info
triggering the crash. Originally we were dealing with a local variable, but as
these require a running process to display, I changed it to use a global one
instead.

SHT_NOTE is the section that consists of
namesz, descsz, type, name + padding, desc + padding data.
This patch teaches yaml2obj, obj2yaml to dump and parse them.

This patch implements the section how it is described here:
https://docs.oracle.com/cd/E23824_01/html/819-0690/chapter6-18048.html
Which says: "For 64–bit objects and 32–bit objects, each entry is an array of 4-byte words in
the format of the target processor"

The official specification is different
http://www.sco.com/developers/gabi/latest/ch5.pheader.html#note_section
And says: "n 64-bit objects (files with e_ident[EI_CLASS] equal to ELFCLASS64), each entry is an array
of 8-byte words in the format of the target processor. In 32-bit objects (files with e_ident[EI_CLASS]
equal to ELFCLASS32), each entry is an array of 4-byte words in the format of the target processor"

Since LLVM uses the first, 32-bit way, this patch follows it.

We were already going to all of the trouble of computing maximum constant exit counts for each loop exit, we might as well expose them through the API.  The change in IndVars is mostly to demonstrate that the wired up code works, but it als very slightly strengthens the transform.  The strengthened case is rather narrow though: it requires one exactly analyzeable exit, one imprecisely analyzeable exit (with the upper bound less than the precise one), and one unanalyzeable exit.  I coudn't construct a reasonably stable test case.

This does increase the memory usage of the BackedgeTakenCount by a factor of 2 in the worst case.

* We would previously minimize _every_ file opened by clang, even module maps

  would be better if we knew which files clang intended to open as a source

  creating that directory. If we cache that failure then the subsequent pcm
  load doesn't see the module cache and fails.

Overall this still leaves us building minmized modules on disk during scanning.

[CMake] Remove unused variable LLDB_TEST_CXX_COMPILER

CMake allows you to set a custom CXX compiler for the API test suite.
However, this variable is never used, because dotest uses the same
compiler to build C and CXX sources.

I'm not sure if this variable was added with the intention of supporting
a different compiler or if this is just a remnant of old functionality.
Given that this hasn't been working for a while, I assume it's safe to
remove.
