Benjamin Kramer 4e36e5bb4c Use realloc instead of malloc+memcpy when growing a POD SmallVector. A smart 
realloc implementation can try to expand the allocated memory block in-place,
avoiding the copy.

Nate Begeman 4904e32d46 Since the enum values for each arch's builtins overlap, it is not appropriate to check them when compiling or other archs. Fixes a problem where compiling for NEON would use x86 sema rules.

Nate Begeman a011002195 Extend __builtin_shufflevector to expose the full power of the llvm shufflevector instruction. This means it can now be used for vector truncation and concatenation. This will be used for the ARM NEON implementation.

Bob Wilson 846bd7992c Further changes for Neon vector shuffles: 
- change isShuffleMaskLegal to show that all shuffles with 32-bit and 64-bit
  elements are legal
- the Neon shuffle instructions do not support 64-bit elements, but we were
  not checking for that before lowering shuffles to use them
- remove some 64-bit element vduplane patterns that are no longer needed

Bob Wilson 7149cfcda3 Fix a mistake in my previous change r105437: don't access operand 2 and assume 
that it is an immediate before checking that the instruction is an
EXTRACT_SUBREG.

Daniel Dunbar 24e52992c0 Driver: Support invoking Clang on .ll or .bc inputs. 
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o').

It is now possible to do something like:
  $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ...
  $ clang -c t.ll -o t.o ... assorted other compile flags ...
and expect that the output will be almost* identical to:
  $ clang -c t.c -o t.o ... assorted other compile flags ...
because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend.

*: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally.

Daniel Dunbar 6f8362c6bf Frontend: Add CodeGenAction support for handling LLVM IR. 
- This magically enables using 'clang -cc1' as a replacement for most of 'llvm-as', 'llvm-dis', 'llc' and 'opt' functionality.

For example, 'llvm-as' is:
  $ clang -cc1 -emit-llvm-bc FOO.ll -o FOO.bc
and 'llvm-dis' is:
  $ clang -cc1 -emit-llvm    FOO.bc -o -
and 'opt' is, e.g.:
  $ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
  $ clang -cc1 -S -o - FOO.ll

The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

Daniel Dunbar 9507f9cc05 Frontend: Add FrontendAction support for handling LLVM IR inputs. 
- These inputs follow an abbreviated execution path, but are still worth handling by FrontendAction so they reuse all the other clang -cc1 features.
