It is still possible to if-convert if the tail block has extra
predecessors, but the tail phis must be rewritten instead of being
removed.

The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain  multiple instructions.

This happens with asm blocks

__asm {
  mov ebx, eax
  mov ecx, ebx
}

or when multiple asm statements are adjacent to one another

__asm mov ebx, eax
__asm mov ecx, ebx

and

__asm mov ebx, eax __asm mov ecx, ebx

Currently, asm blocks are not properly handled.

This was causing unnecessary spills/restores of callee saved registers.

Fixes PR13572.

Do not optimize (or (and X,Y), Z) into BFI and other sequences if the AND ISDNode has more than one user.

'templated' declaration for a function or class template to refer to
the function or class template itself, to which the documentation will
be attached. Fixes PR13593.

current directory, propagate the framework and in-index-header-map
from the including header's information down to the included header's
information. Fixes <rdar://problem/11261291>.

As with everything header-map related, we can't really test this in
isolation within Clang, so it's tested elsewhere.

[asan] remove the code for --asan-merge-callbacks as it appears to be a bad idea. (partly related to Bug 13225)

[ASan] add __asan_set_on_error_callback into force_interface_symbols (thanks to cool test by glider@)

Patch constributed by Michel Moren in http://llvm.org/bugs/show_bug.cgi?id=13592 .  Fixes is_convertible<From, To> when To is an abstract type.

[ASan] Add __asan_set_on_error_callback() interface function that allows user to set a callback to be called right when ASan detects an error

[ASan] If ASan finds second error report, wait for some time and die (instead of running in a busy loop) to make sure ASan won't hang if it finds error while reporting an error in the same thread

Previously, we used VLD1.32 in all cases, however there are both 16 and 64-bit
accesses being selected, so we need to use an appropriate width load in those
cases.

Remove the LowerMMXCONCAT_VECTORS function. It could never execute because there are no legal 64-bit vector types that could be used as inputs to a 128-bit concat_vectors. Remove a target specific SDNode and its patterns that become unused as a result.
