Paul Floyd d4affb0ab7 Make operator new aligned more like the standalone versions 
If the alignment is not a power of two return nullptr for the
nothrow overload and bomb for the throwing overload.

/* ---------------------------------------------------------------------
ALL THE CODE IN THIS FILE RUNS ON THE SIMULATED CPU.
These functions are drop-in replacements for malloc() and friends.
They have global scope, but are not intended to be called directly.
See pub_core_redir.h for the gory details.
This file can be linked into the vg_preload_<tool>.so file for any tool
that wishes to know about calls to malloc(). The tool must define all
the functions that will be called via 'info'.
It is called vg_replace_malloc.c because this filename appears in stack
traces, so we want the name to be (hopefully!) meaningful to users.
IMPORTANT: this file must not contain any floating point code, nor
any integer division. This is because on ARM these can cause calls
to helper functions, which will be unresolved within this .so.
Although it is usually the case that the client's ld.so instance
can bind them at runtime to the relevant functions in the client
executable, there is no guarantee of this; and so the client may
die via a runtime link failure. Hence the only safe approach is to
avoid such function calls in the first place. See "#define CALLOC"
below for a specific example.
A useful command is
for f in `find . -name "*preload*.so*"` ; \
do nm -A $f | grep " U " ; \
done
to see all the undefined symbols in all the preload shared objects.

/* 2 Apr 05: the Portland Group compiler, which uses cfront/ARM style
mangling, could be supported properly by the redirects in this
module. Except we can't because it doesn't put its allocation
functions in libpgc.so but instead hardwires them into the
compilation unit holding main(), which makes them impossible to
intercept directly. Fortunately those fns seem to route everything
through to malloc/free.
mid-06: could be improved, since we can now intercept in the main
executable too.

/* The replacement functions are running on the simulated CPU.
The code on the simulated CPU does not necessarily use
all arguments. E.g. args can be ignored and/or only given
to a NON SIMD call.
The definedness of such 'unused' arguments will not be verified
by memcheck.
The macro 'TRIGGER_MEMCHECK_ERROR_IF_UNDEFINED' allows
memcheck to detect such errors for the otherwise unused args.
Apart of allowing memcheck to detect an error, the macro
TRIGGER_MEMCHECK_ERROR_IF_UNDEFINED has no effect and
has a minimal cost for other tools replacing malloc functions.
Creating an "artificial" use of _x that works reliably is not entirely
straightforward. Simply comparing it against zero often produces no
warning if _x contains at least one nonzero bit is defined, because
Memcheck knows that the result of the comparison will be defined (cf
expensiveCmpEQorNE).
Really we want to PCast _x, so as to create a value which is entirely
undefined if any bit of _x is undefined. But there's no portable way to do
that.

// This doesn't look thread-safe, but it should be ok... Bart says:

// Every program I know of calls malloc() at least once before calling
// pthread_create(). So init_done gets initialized before any thread is
// created, and is only read when multiple threads are active
// simultaneously. Such an access pattern is safe.
//
// If the assignment to the variable init_done would be triggering a race
// condition, both DRD and Helgrind would report this race.
//
// By the way, although the init() function in
// coregrind/m_replacemalloc/vg_replace_malloc.c has been declared
// __attribute__((constructor)), it is not safe to remove the variable
// init_done. This is because it is possible that malloc() and hence
// init() gets called before shared library initialization finished.
