44b0f7b615 driver/gen/ir: clang-format the world 
This uses the LLVM style, which makes sense for sharing code
with other LLVM projects. The DMD code we use will soon all
be in D anyway.

2d959ea540 Make use of C++11 range-based for 
Should be available now that support for LLVM < 3.5 has been dropped.

60d676e2a1 Drop support for LLVM < 3.5 
This allows to clean up the code a little.

2cdbe58d86 Default enable attribute cx16 (-mattr=+cx16). 
This enables code generation for cmpxchg16b instruction which is
not available on very old 64bit CPUs.

The user can change this be choosing a different cpu (`-mcpu=...`)
or by explicitly disabling the attribute (`-mattr=-cx16`).

bbe3c279f1 LLVM 3.8: Access to data layout from llvm::TargetMachine has changed. 
This changes only a small fraction of the code.

2331889669 MIPS: Implement ABI handling. 
Adds a new command line option -mabi= and uses the value to compute
the ABI to use. Adds the ABI to linker and assembler invocation, too.
Allows consistent invocation of the whole tool chain.

afe6051ead LLVM 3.7: Fix MIPS ABI definition. 
Detection of EABI is still missing.

82a76cf3f8 LLVM 3.7: TargetOptions.UseSoftFloat is gone. 
A function attribute use-soft-float with values true or false is used instead.

This commi only ensures that LDC compiles with LLVM 3.7. The possible semantic
change needs to be evaluated.

f554c322a8 Lookup default float-abi for thumb same as arm 
Was always defaulting thumb to soft, now uses same rules for arm.  The
end result is that thumbv7-apple-ios now defaults to softfp correctly.

(cherry picked from commit e0cf8e85c2e42f382742c326f8963b8bf779df8c)

3c9da62ea3 Set version ARM_SoftFP 
Set versions ARM_SoftFP & D_HardFloat instead of ARM_SoftFloat &
D_SoftFloat for option -mfloat-abi=softfp (function calls use soft float
ABI but using hardware floating point instruction).

e4fee1116a ARM: Use -arm-enable-ehabi(-descriptors).

flags it does for C++/Clang, at least in simple cases.

359f6c585a CPU detection for ARM. 
This is not perfect yet, as lookupTarget wipes out any more
specific arch info (e.g. armv8) the triple might have.

02abf028f8 Don't require -triple when using -march. 
There is really no reason we should, and I couldn't find out
why that check was added back in 2009.

Also cleaned up the code a bit now that the LLVM 3.0 branches
are gone.
