First step toward supporting header modifications: adding a flag that turns on
such modifications. Eventually header modifications will be on by default but
until all the kinks can be worked out, they must be explicitly enabled.

Refactored how global options are passed to Transforms to avoid widespread
changes every time a new global option is added.

Tests updated to reflect new interface.

condition in two different processes (with the
same target) could cause crashes.  Now the breakpoint
condition is always evaluated (and possibly parsed)
by one thread at a time.

that is patterned after its parent TestInferiorCrashing.py.

- The xfail decorator limits the xfail to tool-chains that support this compiler option.
- Included a TODO concerning the platform-specific behavior when 'next' is issued after a crash.
- Toggling -fomit-frame-pointer results in an xpass as mentioned in pr15415.

Thanks to Daniel for the review, and Samuel for the bug report and reproducer.

from the LC_DATA_IN_CODE load command.  And when disassembling print
the data in code formatted for the kind of data it and not disassemble those
bytes.

I added the format specific functionality to the derived class MachOObjectFile
since these tables only appears in Mach-O object files. This is my first
attempt to modify the libObject stuff so if folks have better suggestions
how to fit this in or suggestions on the implementation please let me know.

Before, clang-format would happily move a trailing block comment to a
new line, which normally changes the perceived binding of that comment.

E.g., it would move:
void f() { /* comment */
  ...
}
to:
void f() {
  /* comment */
  ...
}

* Documented new command-line options.
* Moved usage to a new page.
  * Usage now split into general options and transform-related options.
* Main Migrator page now contains getting started and getting involved
  information.
  * Also included a JIRA issue collector button for logging bugs.

- For instance, allows 'gcc' to match x86-64-linux-gnu-gcc as required on some Debian builds.
- Also adds doc-strings and a more consistent naming convention for related helpers.
