Arnold Schwaighofer 9ccea99165 Added tail call optimization to the x86 back end. It can be 
enabled by passing -tailcallopt to llc.  The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

Dale Johannesen c0154c06d6 First round of ppc long double. call/return and 
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

Rafael Espindola 6c04ac1db0 Refactor the memcpy lowering for the x86 target. 
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

Gordon Henriksen c23b66c58b Added C and Ocaml bindings for functions, basic blocks, and 
instruction creation. No support yet for instruction introspection.

Also eliminated allocas from the Ocaml bindings for portability,
and avoided unnecessary casts.

Dan Gohman 31599685c7 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

is transformed into

U=min(N,X); L=max(A,Y);
