Dan Gohman 18fa17cf3d Fix the folding of floating-point math library calls, like sin(infinity),
so that it detects errors on platforms where libm doesn't set errno.
It's still subject to host libm details though.

Daniel Dunbar 8fa86b1a44 Driver/DarwinClang: The new toolchain definition is going to drop the -L inside
the GCC dir. Unfortunately, this breaks -lstdc++ on SnowLeopard, etc. because
the libstdc++ dylib was hiding there. Workaround this by providing the path to
the right -lstdc++.6 (the only version used in recent memory) if we can't see an
obvious -lstdc++, but can find = -lstdc++.6.

John McCall 7f9c92a9a0 When emitting a new-expression inside a conditional expression,
the cleanup might not be dominated by the allocation code.
In this case, we have to store aside all the delete arguments
in case we need them later.  There's room for optimization here
in cases where we end up not actually needing the cleanup in
different branches (or being able to pop it after the
initialization code).

Also make sure we only call this operator delete along the path
where we actually allocated something.

Fixes rdar://problem/8439196.

Daniel Dunbar 2cc3f17a26 Driver: Add magic handling for "reserved library names", starting with
-lstdc++. This is the best gross solution for a gross problem.

This issue is that historically, GCC has add -L options to its internally
library directories. This has allowed users and platforms to end up depending on
the layout of GCC's internal library directories.

We want to correct this mistake by eliminating that -L, but this means that
existing libraries which are in the GCC lib dir won't be found. We are going to
handle this by treating those -l names as "reserved", and requiring toolchains
to know how to add the right full path to the reserved library.

The immediately side effect of this is that users trying to use -L to find their
own -lstdc++ will need to start using -nostdlib (which is a good idea
anyway). Another side effect is that -stdlib=libc++ -lstdc++ will now do the
"right" thing, for curious definitions of right.

Douglas Gregor 009f69979a When dealing with an anonymous enumeration declared in function
prototype scope, temporarily set the context of the enumeration
declaration to the translation unit. We do the same thing for
parameters, until we have an actual function declaration on which to
hang them. Fixes <rdar://problem/8435682>.

There is more work to do in this area, since we have existing bugs
with tags being declared/defined in function parameter lists. This fix
is correct, and we'll end up extending it when we deal with those
existing bugs.

Owen Anderson c33cdcfd80 Revert r114097, adding back in the assertion against replacing an Instruction by itself. Now that CorrelatedValuePropagation is
more careful not to call SimplifyInstructionsInBlock() on an unreachable block, the issue has been fixed at a higher level.  Add
a big warning to SimplifyInstructionsInBlock() to hopefully prevent this in the future.

Daniel Dunbar ed23de3348 IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed

 - This fixes the ABI convenient, but breaks codegen since we now have
   underaligned arguments. Marginal improvement overall though, and will be
   fixed in next commit.

Dale Johannesen f95f59a0c2 When substituting sunkaddrs into indirect arguments an asm, we were
walking the asm arguments once and stashing their Values.  This is
wrong because the same memory location can be in the list twice, and
if the first one has a sunkaddr substituted, the stashed value for the
second one will be wrong (use-after-free).  PR 8154.

Owen Anderson 140296f5c0 It is possible, under specific circumstances involving ptrtoint ConstantExpr's, for LVI to end up trying to merge
a Constant into a ConstantRange.  Handle this conservatively for now, rather than asserting.  The testcase is
more complex that I would like, but the manifestation of the problem is sensitive to iteration orders and the state of the
LVI cache, and I have not been able to reproduce it with manually constructed or simplified cases.

Fixes PR8162.
