Why? Debugger::FormatPrompt() would run through the format prompt every time and parse it and emit it piece by piece. It also did formatting differently depending on which key/value pair it was parsing.
The new code improves on this with the following features:
1 - Allow format strings to be parsed into a FormatEntity::Entry which can contain multiple child FormatEntity::Entry objects. This FormatEntity::Entry is a parsed version of what was previously always done in Debugger::FormatPrompt() so it is more efficient to emit formatted strings using the new parsed FormatEntity::Entry.
2 - Allows errors in format strings to be shown immediately when setting the settings (frame-format, thread-format, disassembly-format
3 - Allows auto completion by implementing a new OptionValueFormatEntity and switching frame-format, thread-format, and disassembly-format settings over to using it.
4 - The FormatEntity::Entry for each of the frame-format, thread-format, disassembly-format settings only replaces the old one if the format parses correctly
5 - Combines all consecutive string values together for efficient output. This means all "${ansi.*}" keys and all desensitized characters like "\n" "\t" "\0721" "\x23" will get combined with their previous strings
6 - ${*.script:} (like "${var.script:mymodule.my_var_function}") have all been switched over to use ${script.*:} "${script.var:mymodule.my_var_function}") to make the format easier to parse as I don't believe anyone was using these format string power user features.
7 - All key values pairs are defined in simple C arrays of entries so it is much easier to add new entries.
These changes pave the way for subsequent modifications where we can modify formats to do more (like control the width of value strings can do more and add more functionality more easily like string formatting to control the width, printf formats and more).

Both LLDB and LLGS are leaking file descriptors into the debugged process. This plugs the leak by

The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.
Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).

This was causing problems on clang 602 branches that use MemoryObjects to as the container for opcode bytes instead of a plain array of bytes. So we were asking for 3 bytes to be disassembled at address 0xffffffffffffffff which would cause an unsigned overflow and cause the MemoryObject to refuse to read anymore bytes.

We were referring to hardcoded paths /bin/ls and /bin/cat. For
the purposes of this test, the actual value it's set to doesn't
matter, and it might as well be a non-existent path. All that
matters is that the before and after values have to match, and
that trailing whitespace is stripped. On Windows FileSpec
(correctly) converts /bin/ls to D:\bin\ls though, so the before
and after values won't match. So this patch just correctly builds
up a valid path in a platform-agnostic manner, and verifies that
it matches before and after the set.

Also, keep the hit count for the breakpoint in the breakpoint. We were

Because of the way they are created, synthetic children cannot (in general) have a sane expression path
A solution to this would be letting the parent front-end generate expression paths for its children
Doing so requires a significant amount of refactoring, and might not always lead to better results (esp. w.r.t. C++ templates)
This commit takes a simpler approach:
- if a synthetic child is of pointer type and it's a target pointer, then emit *((T)value)
- if a synthetic child is a non-pointer, but its location is in the target, then emit *((T*)loadAddr)
- if a synthetic child has a value, emit ((T)value)
- else, don't emit anything
