20a9ed0e20 Parameter attributes on invoke calls were being lost due to the wrong 
attribute index being used.  Fix proposed by Anton Korobeynikov, who
asked me to implement and commit it for him.  This is PR1398.

d1534330ee Propagate alignment/volatility in two places. 
Implement support for expanding a bitcast from an illegal vector type to
a legal one (e.g. 4xi32 -> 4xf32 in SSE1).  This fixes PR1371 and

8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

248de25fb5 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.

85e1cac6b7 memory operands that have a direct operand should have their stores created 
before the copies into physregs are done.  This avoids having flag operands
skip the store, causing cycles in the dag at sched time.  This fixes infinite
