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.

  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".

the linker. This matches what GCC does with its -fmerge-constants
option, which is enabled at most -O levels.

Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

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.
