Minor cleanup.
Remove dead code.
Remove code for unimplemented goto-into-asm check.

The check was never fully implemented. We need to look into
this again, as currently we fail with a fairly unintellegible
LLVM ICE (added as GitHub #).
Fix inline asm labels in template functions.

This is a giant kludge to avoid a redesign of the inline asm
handling code. I'd be glad if somebody came up with a better
solution.

GitHub: Fixes #340.
Added -float-abi and auto-detection logic for ARM.

Even though this argument design conflates two separate concepts
(ABI and hardware/software implementation), I chose to go
with it since users are liekly know it from GCC and the
combination of softloat operations with hardfloat ABI makes
no sense.

I didn't implement it for old LLVM versions, as ARM EABI
exception handling requires LLVM 3.3+ anyway, without which
LDC would be useless anyway.
Merge pull request #344 from klickverbot/float-abi

Added -float-abi and auto-detection logic for ARM.
Merge pull request #345 from klickverbot/template-function-label

Fix inline asm labels in template functions.
Fix ARM default floating-point ABI.

It shouldn't really matter, as we probably aren't going to
support anything but AAPCS anytime soon.
LLVM pre-3.2 does not have llvm::Triple::Android.

Strangely enough, the Travis pull request status was
definitely green before I merged it in.
Merge in test cases for GitHub issue #340.
Fix for issue #328.

The wrong pointer is passed to the landing pad. This wrong pointer is used
if the stack unwinding resumes.
Add test case for issue #328
Update catch landingpad codegen to match latest druntime change.
Merge pull request #348 from klickverbot/fix-eh

Update catch landingpad codegen to match latest druntime change.
Revert -float-abi implementation.

The new command line option conflicted with a builtin LLVM 3.0
one. The functionality will be added back in after the 0.11.0
release branch has been created.

This reverts commit 6a1bc70bd7fe15cf9c9d8a4fce2ff7a6ac6d7fdc and
subsequent fixes.
