81da02b553 Make tail merging the default, except on powerPC. There was no prior art 
for a target-dependent default with a command-line override; this way
should be generally usable.

8dd86c14d4 More effective breakdown of memcpy into repeated load/store. These are now 
in the order lod;lod;lod;sto;sto;sto which means the load-store optimizer
has a better chance of producing ldm/stm.  Ideally you would get cooperation
from the RA as well but this is not there yet.

1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

4222d806fa Add an "implies" field to features. This indicates that, if the current 
feature is set, then the features in the implied list should be set also.
The opposite is also enforced: if a feature in the implied list isn't set,
then the feature that owns that implies list shouldn't be set either.

dc43a88b81 Fix two classes of bugs: 
1. x86 backend rejected (&gv+c) for the 'i' constraint when in static mode.
  2. the matcher didn't correctly reject and accept some global addresses.
     the right predicate is GVRequiresExtraLoad, not "relomodel = pic".

6f858e250b Sets the section names for fixed-size constants and use the mergeable 
flag for ELF on x86 so that duplicate constants can be eliminated by
the linker. This matches what GCC does with its -fmerge-constants
option, which is enabled at most -O levels.

5c3885ce8e Under normal circumstances, when a frame pointer is not required, we reserve 
argument space for call sites in the function immediately on entry to the
current function. This eliminates the need for add/sub sp brackets around call
sites. However, this is not always a good idea. If the "call frame" is large and
the target load / store instructions have small immediate field to encode sp
offset, this can cause poor codegen. In the worst case, this can make it
impossible to scavenge a register if the reserved spill slot is pushed too far
apart from sp / fp.
