Anton Korobeynikov 2fd24e7713 Reapply 55899: First draft of EH support on x86/64-linux 
Now with fix, which prevents subtle codegen bug to trigger on darwin.
No fix for bug though, it's still there.

Dale Johannesen 67f99f1454 Redo the 3 existing low-precision expansions to 
use float constants.  An oversight by the numerics
people who supplied this.

Duncan Sands 46911f1271 Reapply 55859. This doesn't change anything as 
long as the callgraph is correct.  It checks

Bill Wendling 5f7371d7b1 Revert my previous change -- the subtraction of two constants was a no-op 
before. This is taken care of in the selection DAG pass. In my opinion, this
should be in one place or the other. I.e., it should probably be removed from
the DAG combiner (along with the other arithmetic transformations on constants
that are essentially no-ops).

Evan Cheng 6c8f55c841 Initial fastisel call support for C, Fast, and X86_FastCall calling conventions. It's meant to handle "simple" calls, i.e. no byval, structret, etc. It doesn't support multi-result returns either. 
Not yet turned on, it needs to support sext / zext of arguments and result.

Evan Cheng 615739b991 - Doh. Pass vector by value is bad. 
- Add a AnalyzeCallResult specialized for calls which produce a single value. This is used by fastisel.

Duncan Sands 95c2a7848a When PruneEH turned an invoke into an ordinary 
call (thus changing the call site) it didn't
inform the callgraph about this.  But the
call site does matter - as shown by the testcase,
the callgraph become invalid after the inliner
ran (with an edge between two functions simply
missing), resulting in wrong deductions by
GlobalsModRef.

Eli Friedman a9c52c8219 Fix for PR2687: Add patterns to match sint_to_fp and fp_to_sint for <2 x 
i32>.  This is a little messy, but it works.

We should really get rid of the intrinsics, though, since they map
perfectly well to standard LLVM instructions.
