AsmParser: add support for .end directive

The .end directive indicates the end of the file.  No further instructions are
processed after a .end directive is encountered.

One potential (glaringly obvious) optimisation that could be pursued here is to
extend MCAsmParser with a DiscardRemainder method to avoid processing lexemes to
the end of the file.  It was unclear at this point if that would be worth
adding, and could easily be added in a follow on change.

ARM: set default float ABI based on triple.

Clang sets the float-abi target option manually, but no longer
annotates each function with its ABI. This can lead to confusing
mistmatch between "clang -emit-llvm | llc" and normal clang
invocations.

Besides which, gnueabihf actually *is* hard-float. Defaulting to soft
was just perverse.

One ppc32-darwin, a i64 inside a structure can have 32 bit alignment.

Thanks for Iain Sandoe for testing this with the original gcc.

Clang was already getting this right.

Fix f64 and f128 for ppc-darwin.

This patch adds -f64:32:64 to 32 bit ppc darwin since a f64 inside a
structure are only 32 bit aligned.

The patch also drop -f128:64:128 from all ppc darwin, since f128 is
128 bit aligned.

[arm] Rename Tag_VFP_arch to Tag_FP_arch.

According to "Addenda to ABI for ARM architecture", Tag_FP_arch is the
new name for the equivalent Tag_VFP_arch.  This commit renames
Tag_VFP_arch to Tag_FP_arch.

[CMake] Don't put every project's tblgen executable in the LLVM bin directory.

This changes Clang standalone builds so that clang-tblgen lives in
clang/build/bin instead of llvm/build/bin, and so that with the Xcode
generator it's in clang/build/bin/Debug instead of llvm/build/bin/Debug/Debug/.
Yes, really.

llvm-cov: Print coverage summary to STDOUT.

File summaries will now be optionally outputted which will give line,
branching and call coverage info. Unfortunately, clang's current
instrumentation does not give enough information to deduce function
calls, something that gcc is able to do. Thus, no calls are always
outputted to be consistent with gcov output.

Also updated tests.
