Rafael Espindola 66aa045fd9 Add a -fuse-init-array option to cc1 and map to the UseInitArray target
option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.

Rafael Espindola ca3e0ee8b3 Move the support for using .init_array from ARM to the generic
TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM,
on X86 it is not easy to find out if .init_array should be used or not, so
the decision is made via TargetOptions and defaults to off.

Add a command line option to llc that enables it.

Kaelyn Uhrain 9ea8f7e6c5 Improve the error message when a function overload candidate is rejected
because it expects a reference and receives a non-l-value.

For example, given:

  int foo(int &);
  template<int x> void b() { foo(x); }

clang will now print "expects an l-value for 1st argument" instead of
"no known conversion from 'int' to 'int &' for 1st argument". The change
in wording (and associated code to detect the case) was prompted by
comment #5 in PR3104, and should be the last bit of work needed for the
bug.

Jordan Rose 8cea63c5cd Change -Winternal-linkage-in-inline from ExtWarn to Warning in C++.
Per post-commit review, it's not appropriate to use ExtWarn in C++, because
we can't prove that the inline function will actually be defined in more than
one place (and thus we can't prove that this violates the ODR).

This removes the warning entirely from uses in the main source file in C++.

Jordan Rose 28cd12f265 Support -Winternal-linkage-in-inline in C++ code.
This includes treating anonymous namespaces like internal linkage, and allowing
const variables to be used even if internal. The whole thing's been broken out
into a separate function to avoid nested ifs.

Jordan Rose 2fa69ef934 Add new tool 'diag-build' for showing enabled warnings in a project.
diag-build acts as a wrapper for 'diagtool show-enabled', in the same way
that scan-build acts as a wrapper for the static analyzer. The common case is
simple: use 'diag-build make' or 'diag-build xcodebuild' to list the warnings
enabled for the first compilation command we see. Other build systems require
you to manually specify "dry-run" and "use $CC and $CXX"; if there is a build
system you are interested in, please add it to the switch statement.

diag-build is fairly stupid right now, but it serves its basic purpose.
Hopefully it can grow to meet any additional requirements.

This simplifies the code a little bit, since these functions all took a

Jordan Rose edff020011 Allow internal decls in inline functions if the function is in the main file.
This handles the very common case of people writing inline functions in their
main source files and not tagging them as inline. These cases should still
behave as the user intended. (The diagnostic is still emitted as an extension.)

I'm reworking this code anyway to account for C++'s equivalent restriction in
[basic.def.odr]p6, but this should get some bots back to green.

Joel Jones 3237ce737e This change handles a another case for generating the bic instruction
when a compile time constant is known.  This occurs when implicitly zero 
extending function arguments from 16 bits to 32 bits.  The 8 bit case doesn't
need to be handled, as the 8 bit constants are encoded directly, thereby
not needing a separate load instruction to form the constant into a register.

Chandler Carruth a1da0bf5ef Add a regression test for the bug exposed by r158087, which has been
temporarily reverted.

This test is annoyingly overspecified, but I don't know of another way
to thoroughly test the saving and restoring of the registers. While this
will have to be adjusted even with the issue fixed in order to re-apply
r158087, those adjustments should very clearly indicate that it is still
correct (%esp getting restored prior to pops), whereas without it, this
case can easily slip under the radar.

Still, any suggestions for improvements are very welcome.

All credit to Matt Beaumont-Gay for reducing this out of an insane
Address Sanitizer crash to a reasonably small seg-faulting C program
when built with -mstackrealign. I just reduced it to IR, which was much
simpler. =]

Chandler Carruth 2cc11fd8c7 Temporarily revert r158087.
This patch causes problems when both dynamic stack realignment and
dynamic allocas combine in the same function. With this patch, we no
longer build the epilog correctly, and silently restore registers from
the wrong position in the stack.

Thanks to Matt for tracking this down, and getting at least an initial
test case to Chad. I'm going to try to check a variation of that test
case in so we can easily track the fixes required.
