a function has any function calls.

Charles Davis 936847ddf5 Revert r132111. I built Release (without Asserts), so I didn't know about the 
assert that prevented setting alignment on section creation.

Charles Davis 006e1c39d0 Test .seh_startchained and .seh_endchained parsing. 
Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

Andrew Trick 7fac79e255 indvars: incremental fixes for -disable-iv-rewrite and testcases. 
Use a proper worklist for use-def traversal without holding onto an
iterator. Now that we process all IV uses, we need complete logic for
resusing existing derived IV defs. See HoistStep.

Jakob Stoklund Olesen 25d5745cc5 Add a RAGreedy::canEvict function. 
This doesn't change functionality (much), but it allows for a more fine-grained
eviction policy. The current policy only compares spill weights, and that is not
always the best thing to do.  Spill weights are designed to serve linear scan,
and they don't consider live range splitting.

Add a mechanism so canEvict() can request that a live range be evicted and
split/spilled. This is to avoid infinite eviction loops.

Eli Friedman c70355195c Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent. 
The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).

Charles Davis 2f6ecea19d Add tests for .seh_setframe and .seh_handlerdata parsing. Fix issues with 
them.

I had to add a special SwitchSectionNoChange method to MCStreamer just for
.seh_handlerdata. If this isn't OK, please let me know, and I'll find some
other way to fix .seh_handlerdata streaming.

Francois Pichet f83114dceb Fix 3 MSVC warnings: 
'void (__cdecl *)()' differs in parameter lists from 'void (__cdecl *)(void)'

atexit really expects a "void f(void)" function.

Francois Pichet 58b09c9366 Fix MSVC warning: "is out of range for enum constant" 
MSVC doesn't support 64 bit enum. 
OpcodeMask is not used anywhere in the code base.

Rafael Espindola 33dacdfe66 Fix some issues Duncan found in the previous commit. 
I kept the reference to the ABI since that is the common case. The
-fno-asynchronous-unwind-tables option is a user controlled way of breaking
the ABI.

Cameron Zwarich 310b3472ec Change the order of tBX's operands so that the predicate operands come after the 
target register, matching BX. I filed this bug because I was confused at first:

Rafael Espindola fc9bae6f8b Replace the -unwind-tables option with a per function flag. This is more 
LTO friendly as we can now correctly merge files compiled with or without
-fasynchronous-unwind-tables.
