Summary:
this also gets rid of a compiler warning in release builds by using a dynamically allocated
buffer. Therefore, a size assertion is not necessary (and probably should have been an error in
the first place).

When launching argdumper, there are a few problems with the
current logic. First, on Windows, the file is called
argdumper.exe, not argdumper. Second, Windows paths have
backslashes in them, and JSON treats <backslash><char> as an
escape sequence. To fix the second problem, on Windows we
convert backslashes to forward slashes, since backslash isn't
a valid filename character anyway this shouldn't be a problem.

llvm::StringRef doesn't make a copy of a string, it just holds a
reference. When special_directions_stream went out of scope,
special_directions was holding on to a stale pointer.
Moving special_directions_stream into a higher scope to keep
special_directions pointing to a valid string.

CopyContext is necessary to safely get the XState, but LLDB doesn't currently
use the XState. CopyContext is available as of Windows 7 SP1, so it can't be
used on Vista. Furthermore, it requires the Windows 8 SDK it compile,
making the baseline for compiling and running LLDB higher than necessary.

Previously we would create the extension module as a post-build
step of creating liblldb. As part of this process, we created
symlinks and did other stuff.
This had several longstanding issues related to target
dependencies, such as not re-creating the symlink if liblldb.dll
failed to link, or if the build was Ctrl+C'ed from.
Then, the script that creates the symlinks began to grow to
include other things, such as argdumper, and it would try to
create symlinks before it had finished building the targets it
needed to symlink to.
This patches addresses all of these problems by creating an
explicit target for the script to run, and making it have a
dependency on all the targets it needs to create symlinks from/to.

Previos version of this patch (see r229148) contained two errors:
* make_symlink_darwin_debug passes 2 arguments into make_symlink, but it required 4 arguments (was fixed by r229159)

As a quick fix, the r229148 and the r229159 were reverted. Now these errors are fixed.

Summary:
Currently we have some settings which treat "\ " on settings set commands specially. E.g., it is
a valid way of specifying an argument of " " to a target. However, this fails if "\ " is the last
argument as CommandObjectSettingsSet strips trailing whitespace. This resulted in a surprising
argument of "\" to the target.
This patch disables the training whitespace removal at a global
level. Instead, for each argument type we locally determine whether whitespace stripping makes
sense. Currently, I strip whitespace for all simple object type except of regex and
format-string, with the rationale that these two object types do their own complex parsing and we
want to interfere with them as least as possible. Specifically, stripping the whitespace of a
regex "\ " will result in a (surprising?) error "trailing backslash". Furthermore, the default
value of dissasembly-format setting already contains a trailing space and there is no way for the
user to type this in manually if we strip whitespace.

GetVariableInfo () collected the values of the variable in a list. But it also
tried to generate the name/value pairs for children. This caused generation of
a wrong value string for may items. This function has been fixed to put value in
the list only.
The handling of --print-value related option has been moved to caller.
GetVariableInfo2 and MIResponseFormVariableInfo3 have been removed. They were
almost the duplicate of functions of similar names. I dont see any difference in
the output of -stack-list-locals and -stack-list-arguments. So these functions
just seemed unnecessary.
Char variable was being printed as a string which caused garbage output. This has
been fixed.
Some misc. cleanup.
Test cases have been added that check -stack-list-locals for struct, array and
pointers. Modified other tests which depended on hard coded line numbers.

For the text offset, use the addr_t type that is used elsewhere to get
these kinds of offsets, and which it is being compared against. This
seems to make things more consistent.

There was a test in the test suite that was triggering the backtrace logging output that requested that the client pass an execution context. Sometimes we need the process for Objective C types because our static notion of the type might not align with the reality when being run in a live runtime.
Switched from an "ExecutionContext *" to an "ExecutionContextScope *" for greater ease of use.
llvm-svn: 228892
Rules for returning "const char *" from functions in the public lldb::SB* API are that you must constify the string using "ConstString(cstr).GetCString()" and return that. This puts the string into a string pool that never goes away. This is only when there is nothing that can hold onto the string. It is OK to specify that a string value lives as long as its SB class counterpart, but this should be made clear in the API if this is done. Many classes already constify their strings (symbol mangled and demangled names, variable names, type names, etc), so be sure to verify you string isn't already constified before you re-constify it. It won't do any harm to re-constify it, it will just cause you a little performance by having to rehash the string.
llvm-svn: 228867
This removes the rule from the LLDB coding standard about putting

there but can still be problem for some other clients.

A runtime support value is a ValueObject whose only purpose is to support some language runtime's operation, but it does not directly provide any user-visible benefit
As such, unless the user is working on the runtime support, it is mostly safe for them not to see such a value when debugging
It is a language runtime's job to check whether a ValueObject is a support value, and that - in conjunction with a target setting - is used by frame variable and target variable
SBFrame::GetVariables gets a new overload with yet another flag to dictate whether to return those support values to the caller - that which defaults to the setting's value

Because types are not reliably protected against the death of their owners, having ValueObjects lurking around like that past the useful lifetime of their owner processes is a potential source of crashes

- that type is returned from an ARM function that LLDB steps over so we try to figure out the return type
- we try to determine if the type is a homogeneous aggregate type and we crash
