Ed Maste 04a8bab047 Support mips shared object debug info
MIPS's .dyanamic section is read-only.  Instead of using DT_DEBUG for
the pointer to dyld information it uses a separate tag DT_MIPS_RLD_MAP
which points to storage in the read-write .rld_map section, which in
turn points to the dyld information.

Greg Clayton 896005804d <rdar://problem/14146606>
Fixed an issue where environment variables that contained special characters '$' and '#' would hose up the GDB server packet. We now use the QEnvironmentHexEncoded packet that has existed for a long time when we need to. Also added code that will stop sending the QEnvironmentHexEncoded and QEnvironment packets if they aren't supported.

Ed Maste bb59e049ba POSIX dyld: handle extra MIPS link map field
On at least FreeBSD and NetBSD there is an extra field in the dyld link
map struct.  I've left an assert for other OSes (i.e., Linux/mips) until
it's determined if they do the same.

Ed Maste d8cc39e653 POSIX RegisterContext for mips64
Based on the POSIX x86_64 register context.  This is sufficient for opening
a mips64 (big endian) core file.  Subsequent changes will connect the
disassembler, dynamic loader support, ABI, etc.

Ed Maste b0e33d4165 Fix endianness in ObjectFile::CopyData
ObjectFile::CopyData is used to copy a block of target memory to the
caller's buffer (e.g. for "memory read").  This should be a straight
memcpy, and not byte-swapped if the target and host have different
endianness.

Add a new DataExtractor::CopyData() method that performs this straight
copy and use it in ObjectFile::CopyData().

Enrico Granata b1c6c489ca <rdar://problem/14923930>
Constant ValueObjects should clear their description as well as their summary. Rationale being that both can depend on deeper-than-constified data
so both are subject to changes in "unpredictable" ways
To see this consider repeatedly po'ing a persistent variable of a type whose -description result changes at each invocation

This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases

More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff:
this ValueObject does not have a summary
its children have no synthetic children
its children are not a non-empty base class without a summary
its children do not have a summary that asks for children to show up
the aggregate length of all the names of all the children is <= 50 characters
you did not ask to see the types during a printout
your pointer depth is 0

This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?)

Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be)

Sean Callanan ddd7a2a65b Changed the bool conversion operator on ConstString
to be explicit, to prevent horrid things like

std::string a = ConstString("foo")

from taking the path ConstString -> bool -> char
-> std::string.

This fixes, among other things, ClangFunction.

DumpValueObject() 2.0

This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command:
- expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull)
 When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in
(lldb) expr -O -v -- foo
(id) $0 = 0x000000010010baf0 {
    1 = 2;
    2 = 3;
}

 When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in
(lldb) expr -O -- foo
{
    1 = 2;
    2 = 3;
}

- for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display
(lldb) po 5
5
-v also works in this mode
(lldb) expr -O -vfull -- 5
(int) $4 = 5 

On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future
DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed

Test case to follow
