ca05b607b7 Refer to -help instead of --help since this is what tools themselves say. 
Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation.  This doesn't change
every mention of --help, only those which seemed clearly safe.

428b385575 Add a new pass to do llvm.objsize lowering using SCEV. 
Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

4d97e42ba6 enhance bits_storage to work with enums by using a c-style

da4372a3c2 use a c-style cast instead of reinterpret-cast, as sometimes the

fb10587e50 Kill ModuleProvider and ghost linkage by inverting the relationship between 
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

3c2fad1fc6 change Mangler::makeNameProper to return its result in a SmallVector 
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

3f7cf289ed Provide dbgs(), a circular-buffering debug output stream. By default it 
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.

299ec7d3e7 Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

23ac706aab Fix DenseMap iterator constness. 
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

Patch by Victor Zverovich!

531ed64b09 Run the functionattrs pass after the inliner, and not before. 
This makes both logical sense (see below) and increases the
number of functions marked readnone/readonly by about 1-2%
in practice.  The number of functions marked nocapture goes
up by about 5-10%.  The reason it makes sense is shown by
the following example: if you run -functionattrs -inline on
it, then no attributes are assigned.  But if you instead run
-inline -functionattrs then @f is marked readnone because the
simplifications produced by the inliner eliminate the store.

@x = external global i32

define void @w(i1 %b) {
        br i1 %b, label %write, label %return
write:
        store i32 1, i32 *@x
        br label %return
return:
        ret void
}

define void @f() {
        call void @w(i1 0)
        ret void
}

dc9cf48396 fix two strange things in the default passmgr: 
1. we'd run simplifycfg at the very start, even though
the per function passes have already cleaned this up.

2. In the main per-function pipeline that is interlaced with inlining 
   etc, we would do instcombine, jump threading, simplifycfg *before*
   doing SROA.  SROA is much more likely to expose opportunities for
   these passes than they are for SROA, so move SRoA up earlier.

also add some comments.

69549467e3 We currently only run ipsccp at LTO time, which is silly. It subsumes 
ipconstprop and doesn't take much time.  Just run it in its place.

This adds a testcase for it, which I plan to expand to cover other
"integration" cases, where we expect the optimizer to be able to
eliminate various things.  Due to phase order issues we've regressed
in a number of areas and integration tests are the only way I see to
prevent this.

even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.

It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.

fdb36c1a29 Clean up the JITResolver stub/callsite<->function maps. 
The JITResolver maps Functions to their canonical stubs and all callsites for
lazily-compiled functions to their target Functions. To make Function
destruction work, I'm going to need to remove all callsites on destruction, so
this patch also adds the reverse mapping for that.

There was an incorrect assumption in here that the only stub for a function
would be the one caused by needing to lazily compile it, while x86-64 far calls
and dlsym-stubs could also cause such stubs, but I didn't look for a test case
that the assumption broke.

This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of
std::maps.
