GCC and ICC.

Fixes PR13284.

the input vector, it can be bigger (this is helpful for powerpc where <2 x i16>
is a legal vector type but i16 isn't a legal type, IIRC).  However this wasn't
being taken into account by ExpandRes_EXTRACT_VECTOR_ELT, causing PR13220.
Lightly tweaked version of a patch by Michael Liao.

One adds matchers for the various parts of a for loop (initializer, condition,
increment), as well as extending the hasBody matcher to work for while and
do-while loops. The second patch adds an isInteger matcher for types.
The third patch fixes a bug in allOf, where a few of the name chages
(AllOf --> allOf) had been missed.

All matchers come with unit tests.

If a non-unicode locale is used, the unicode character is escaped and any
byte that is in the escaped representation but not the semicolon will
become whitespace.

The demanded bit optimization is actually a pessimization because add -1 would
be codegen'ed as a sub 1. Teach the demanded constant shrinking optimization
to check for negated constant to make sure it is actually reducing the width
of the constant.

Add a command channel to wait on along with the file descriptor the ConnectionFileDescriptor class is managing, so we can always pop ourselves out of our select call regardless of how well behaved the channel we are talking to is.

Results in 'record name is not a string!' diagnostic. Not the best,
but the lack of location information moves it from not very helpful
into completely useless. We're in the Record class when throwing the
error, so just add the location info directly.

UnwindPlans for a function.  This specifically does not use any
previously-generated UnwindPlans so if any logging is performed
while creating the UnwindPlans, it will be repeated.  This is
useful for when an lldb stack trace is not correct and you want
to gather diagnostic information from the user -- they can do 
log enable -v lldb unwind, image show-unwind of the function, and
you'll get the full logging as the UnwindPlans are recreated.

Previously we were using the static type of the base object to inline
methods, whether virtual or non-virtual. Now, we try to see if the base
object has a known type, and if so ask for its implementation of the method.

Modifying the "address" format, which prints a pointer and a description of what it points to, to detect when the deref of that pointer points to something valid. So if you have:

    % cat sp.cpp 
    #include <tr1/memory>

    class A
    {
    public:
        A (): m_i (12) {}
        virtual ~A() {}
    private:
        int m_i;
    };

    int main (int argc, char const *argv[], char const *envp[])
    {
        A *a_pointers[2] = { NULL, NULL };
        A a1;
        A a2;
        a_pointers[0] = &a1;
        a_pointers[1] = &a2;
        return 0;
    }


And you stop at the "return 0", you can now read memory using the "address" format and see:

(lldb) memory read --format address `&a_pointers`
0x7fff5fbff870: 0x00007fff5fbff860 -> 0x00000001000010b0 vtable for A + 16
0x7fff5fbff878: 0x00007fff5fbff850 -> 0x00000001000010b0 vtable for A + 16
0x7fff5fbff880: 0x00007fff5fbff8d0
0x7fff5fbff888: 0x00007fff5fbff8c0
0x7fff5fbff890: 0x0000000000000001
0x7fff5fbff898: 0x36d54c275add2294
0x7fff5fbff8a0: 0x00007fff5fbff8b0
0x7fff5fbff8a8: 0x0000000100000bb4 a.out`start + 52

Note the extra dereference that was applied to 0x00007fff5fbff860 and 0x00007fff5fbff850 so we can see that these are "A" classes.

When WriteFragmentData() case FT_align called
Asm.getBackend().writeNopData() is called, nothing
is done since Mips implementation of writeNopData just
returned "true".

For some reason this has not caused problems in 32 bit
mode, but in 64 bit mode it caused an assert when processing
multiple function units.

The test case included will assert without this patch. It
runs twice with different flags to prevent false positives
due to changes in code generation over time.
