This patch imports the runtime library in the GCC tree, ensures that
-lasan is passed to the linker when -faddress-sanitizer is used and
sets up the build system accordingly.

ChangeLog:

	* configure.ac: Add libsanitizer to target_libraries.
	* Makefile.def: Ditto.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
	* libsanitizer: New directory for asan runtime.  Contains an empty
	tsan directory.

gcc/ChangeLog:

	* gcc.c (LINK_COMMAND_SPEC): Add -laddress-sanitizer to link
	command if -faddress-sanitizer is on.

libsanitizer:

	Initial checkin: migrate asan runtime from llvm.

This patch instruments many memory access patterns through builtins.

Basically, for a call like:

     __builtin_memset (from, 0, n_bytes);

the patch would only instrument the accesses at the beginning and at
the end of the memory region [from, from + n_bytes].  This is the
strategy used by the llvm implementation of asan.

This instrumentation is done for all the memory access builtin
functions that expose a well specified memory region -- one that
explicitly states the number of bytes accessed in the region.

A special treatment is used for __builtin_strlen.  The patch
instruments the access to the first byte of its argument, as well as
the access to the byte (of the argument) at the offset returned by
strlen.

For the __sync_* and __atomic* calls the patch instruments the access
to the bytes pointed to by the argument.

While doing this, I have added a new parameter to build_check_stmt to
decide whether to insert the instrumentation code before or after the
statement iterator.  This allows us to do away with the
gsi_{next,prev} dance we were doing in the callers of this function.

Tested by running cc1 -fasan on variations of simple programs like:

    int
    foo ()
    {
      char foo[10] = {0};

      foo[0] = 't';
      foo[1] = 'e';
      foo[2] = 's';
      foo[3] = 't';
      int l = __builtin_strlen (foo);
      int n = sizeof (foo);
      __builtin_memset (&foo[4], 0, n - 4);
      __sync_fetch_and_add (&foo[11], 1);

      return l;
    }

and by starring at the gimple output which for this function is:

    ;; Function foo (foo, funcdef_no=0, decl_uid=1714, cgraph_uid=0)

    foo ()
    {
      int n;

This patch implements the protection of stack variables.

It lays out stack variables as well as the different red zones,
emits some prologue code to populate the shadow memory as to poison
(mark as non-accessible) the regions of the red zones and mark the
regions of stack variables as accessible, and emit some epilogue code
to un-poison (mark as accessible) the regions of red zones right
before the function exits.

	* Makefile.in (asan.o): Depend on $(EXPR_H) $(OPTABS_H).

	(partition_stack_vars): If i is large alignment and j small
	alignment or vice versa, break out of the loop instead of continue,

	if for small alignment size is different.
	(struct stack_vars_data): New type.
	(expand_stack_vars): Add DATA argument.  Change PRED type to

	if -faddress-sanitizer.
	(defer_stack_allocation): Defer everything for flag_asan.
	(stack_protect_decl_phase_1, stack_protect_decl_phase_2): Take
	size_t index into stack_vars array instead of the decl directly.
	(asan_decl_phase_3): New function.
	(expand_used_vars): Return var destruction sequence.  Adjust

This patch defines a new asan_shadow_offset target macro, instead of
having a mere macro in the asan.c file.  It becomes thus cleaner to
define the target macro for targets that supports asan, namely x86 for
now.  The ASAN_SHADOW_SHIFT (which, along with the asan_shadow_offset
constant, is used to compute the address of the shadow memory byte for
a given memory address) is defined in asan.h.

This patch imports the initial state of asan as it was in the
Google branch.

It provides basic infrastructure for asan to instrument memory
accesses on the heap, at -O3.  Note that it supports neither stack nor
global variable protection.

The rest of the patches of the set is intended to further improve this
base.

gcc/ChangeLog

	* Makefile.in: Add asan.c and its dependencies.
	* common.opt: Add -faddress-sanitizer option.
	* invoke.texi: Document the new flag.
	* passes.c: Add the asan pass.
	* toplev.c (compile_file): Call asan_finish_file.
	* asan.c: New file.
	* asan.h: New file.
	* tree-pass.h: Declare pass_asan.
