Douglas Gregor 0693defea9 When we run into a template parameter that should have a default 
argument but doesn't (because previous template parameters had default
arguments), clear out all of the default arguments so that we maintain
the invariant that a template parameter has a default argument only if
subsequence template parameters also have default arguments.
Fixes a crash-on-invalid <rdar://problem/8913649>.

Greg Clayton 645bf5420d Added support for some new environment variables within LLDB to enable some 
extra launch options:

LLDB_LAUNCH_FLAG_DISABLE_ASLR disables ASLR for all launched processes

LLDB_LAUNCH_FLAG_DISABLE_STDIO will disable STDIO (reroute to "/dev/null")
for all launched processes

LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY will force all launched processes to be
launched in new terminal windows.

Also, don't init python if we never create a script interpreter.

Douglas Gregor 582813596a Fix a horrible bug in our handling of C-style casting, where a C-style 
derived-to-base cast that also casts away constness (one of the cases
for static_cast followed by const_cast) would be treated as a bit-cast
rather than a derived-to-base class, causing miscompiles and
heartburn.

Fixes <rdar://problem/8913298>.

Douglas Gregor c83f9865a0 Implement the restriction that a function with a ref-qualifier cannot 
overload a function without a ref-qualifier (C++0x
[over.load]p2). This, apparently, completes the implementation of
rvalue references for *this.

Bill Wendling 5a13d4fa8f Add support for printing out floating point values from the ARM assembly 
parser. The parser will always give us a binary representation of the floating
point number.

Douglas Gregor a52713096d Improve the extension warning for the use of ref-qualifiers, to 
distinguish them from rvalue references. Using the rvalue-references
warning was weird when the ref-qualifier was '&'.

John McCall 5143d646b9 When mangling a qualified array type, push the qualifiers down to the 
element type.  Fixes rdar://problem/8913416.

Bob Wilson b9b2422e89 Improve the AsmMatcher's ability to handle suboperands. 
When an operand class is defined with MIOperandInfo set to a list of
suboperands, the AsmMatcher has so far required that operand to also define
a custom ParserMatchClass, and InstAlias patterns have not been able to
set the individual suboperands separately.  This patch removes both of those
restrictions.  If a "compound" operand does not override the default
ParserMatchClass, then the AsmMatcher will now parse its suboperands
separately.  If an InstAlias operand has the same class as the corresponding
compound operand, then it will be handled as before; but if that check fails,
TableGen will now try to match up a sequence of InstAlias operands with the
corresponding suboperands.

Douglas Gregor e1a47c1766 Rvalue references for *this: explicitly keep track of whether a 
reference binding is for the implicit object parameter of a member
function with a ref-qualifier. My previous comment, that we didn't
need to track this explicitly, was wrong: we do in fact get
rvalue-references-prefer-rvalues overloading with ref-qualifiers.

David Greene bab5e6ed0e [AVX] Add INSERT_SUBVECTOR and support it on x86. This provides a 
default implementation for x86, going through the stack in a similr
fashion to how the codegen implements BUILD_VECTOR.  Eventually this
will get matched to VINSERTF128 if AVX is available.

Douglas Gregor b2f8aa9556 Rvalue references for *this: allow functions to be overloaded based on 
the presence and form of a ref-qualifier. Note that we do *not* yet
implement the restriction in C++0x [over.load]p2 that requires either
all non-static functions with a given parameter-type-list to have a
ref-qualifier or none of them to have a ref-qualifier.
