This fixes two crashes that appeared in case of:
- A load of a non vectorizable type (e.g. float**)
- An instruction that is not vectorizable (e.g. call)

CompilerInstance::setCodeCompletionConsumer instead, in order to change
the SkipFunctionBodies flag accordingly. Also fixed
setCodeCompletionConsumer to take a reset() to null into account.

turns out that it's actually needed for C++ modules support. Since simplifying
it didn't cause any test failures, I'll add a test for it.

This is not quite sufficient for libstdc++'s <atomic>: we still need
__atomic_test_and_set and __atomic_clear, and may need a more complete
__atomic_is_lock_free implementation.
We are also missing an implementation of __atomic_always_lock_free,
__atomic_nand_fetch, and __atomic_fetch_nand, but those aren't needed
for libstdc++.

get the diagnostic category name from a serialized diagnostic when the version of libclang used
to read the diagnostic file is newer than the clang that emitted the diagnostic file.

As per Jordy's review. Creating a symbol here is more flexible; however
I could not come up with an example where it was needed. (What
constrains can be added on of the symbol constrained to 0?)

- FCOPYSIGN nodes that have operands of different types were not handled.
- Different code was generated depending on the endianness of the target.
Additionally, code is added that emits INS and EXT instructions, if they are
supported by target (they are R2 instructions).

Per discussion with Howard, we are not interested in maintaining
compatibility with older versions of clang.
All tests pass with ToT clang, except for two which assert due to
a pre-existing, unrelated bug.

First we can load the module:
(lldb) command script import /Volumes/work/gclayton/Documents/src/lldb/examples/darwin/heap_find/heap.py
Loading "/Volumes/work/gclayton/Documents/src/lldb/examples/darwin/heap_find/libheap.dylib"...ok
Image 0 loaded.
"heap_ptr_refs" and "heap_cstr_refs" commands have been installed, use the "--help" options on these commands for detailed help.
Lets take a look at the variable "my":
(lldb) fr var *my
(MyString) *my = {
MyBase = {
NSObject = {
isa = MyString
}
propertyMovesThings = 0
}
str = 0x0000000100301a60
date = 0x0000000100301e60
_desc_pauses = NO
}
We can see that this contains an ivar "str" which has a pointer value of "0x0000000100301a60". Lets search the heap for this pointer and see what we find:
(lldb) heap_ptr_refs 0x0000000100301a60
found pointer 0x0000000100301a60: block = 0x103800270, size = 384, offset = 168, type = 'void *'
found pointer 0x0000000100301a60: block = 0x100301cf0, size = 48, offset = 16, type = 'MyString *', ivar = 'str'
(MyString) *addr = {
MyBase = {
NSObject = {
isa = MyString
}
propertyMovesThings = 0
}
str = 0x0000000100301a60
date = 0x0000000100301e60
_desc_pauses = NO
}
found pointer 0x0000000100301a60: block = 0x100820000, size = 4096, offset = 96, type = (autorelease object pool)
found pointer 0x0000000100301a60: block = 0x100820000, size = 4096, offset = 104, type = (autorelease object pool)
Note that it used dynamic type info to find that it was in "MyString" at offset 16 and it also found the ivar "str"!
We can also look for C string values on the heap. Lets look for "a.out":
(lldb) heap_cstr_refs "a.out"
found cstr a.out: block = 0x10010ce00, size = 96, offset = 85, type = '__NSCFString *'
found cstr a.out: block = 0x100112d90, size = 80, offset = 68, type = 'void *'
found cstr a.out: block = 0x100114490, size = 96, offset = 85, type = '__NSCFString *'
found cstr a.out: block = 0x100114530, size = 112, offset = 97, type = '__NSCFString *'
found cstr a.out: block = 0x100114e40, size = 32, offset = 17, type = '__NSCFString *'
found cstr a.out: block = 0x100114fa0, size = 32, offset = 17, type = '__NSCFString *'
found cstr a.out: block = 0x100300780, size = 160, offset = 128, type = '__NSCFData *'
found cstr a.out: block = 0x100301a60, size = 112, offset = 97, type = '__NSCFString *'
found cstr a.out: block = 0x100821000, size = 4096, offset = 100, type = 'void *'
We see we have some objective C classes that contain this, so lets "po" all of the results by adding the --po option:
(lldb) heap_cstr_refs a.out --po

In passing, fix LanguageExtensions to note that C11 and C++11 are no longer
"upcoming standards" but are now actually standardized.
