We had a MCAsmInfoCOFF, but no common class for all the ELF MCAsmInfos before.

This patch fixes PR17506.

No new testcases. However, this patch makes all supported JIT testcases in 
test/ExecutionEngine  pass on Sparc.

[Sparc] Do not hardcode nop in the delay slot of TLS_CALL. Use DelaySlotFiller to fill the delay slot instead.

They haven't been used for a long time. Patch by MathOnNapkins.

This is required because i64 is a legal type but addxcc/subxcc reads icc carry bit, which are 32 bit conditional codes.

llvm-svn: 192054

addx/subx does not modify conditional codes whereas addxcc/subxx does.

[Sparc] Make SPARC instructions' encoding well defined such that TableGen can automatically generate code emitter.

llvm-svn: 191168

[Sparc] Clean up MOVcc instructions so that TableGen can encode them correctly. No functionality change intended.

[Sparc] Clean up branch instructions, so that TableGen can encode branch conditions as well. No functionality change intended.

Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.

Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.

This should fix PR15840.

In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.

This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.

  This assertion is triggered because an integer constant is created with wrong
  type.

This field specifies registers that are preserved across function calls,
but that should not be included in the generates SaveList array.

This can be used ot generate regmasks for architectures that save
registers through other means, like SPARC's register windows.

[Sparc] Use HWEncoding instead of unused Num field in Sparc register definitions. Also, correct the definitions of RETL and RET instructions.

Target/*/CMakeLists.txt: Add the dependency to CommonTableGen explicitly for each corresponding CodeGen.

Without explicit dependencies, both per-file action and in-CommonTableGen action could run in parallel.
It races to emit *.inc files simultaneously.
