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

If call frame is not part of stack frame and no dynamic alloc, eliminateFrameIndex() must adjust SP offset with size of call frames.

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.
