76e60fbe46 Add an ensureMaxAlignment() function to MachineFrameInfo (analogous to
ensureAlignment() in MachineFunction).  Also, drop setMaxAlignment() in
favor of this new function.  This creates a main entry point to setting
MaxAlignment, which will be helpful for future work.  No functionality
change intended.

be0b8939c0 Switch all register list clients to the new MC*Iterator interface.
No functional change intended.

Sorry for the churn. The iterator classes are supposed to help avoid
giant commits like this one in the future. The TableGen-produced
register lists are getting quite large, and it may be necessary to
change the table representation.

This makes it possible to do so without changing all clients (again).

65f7ea8a35 If the alignment of the byval argument is greater than the alignment
of the frame then increase the maximum alignment of the frame to
match.

passed as the fifth parameter, insure it's passed correctly (in R9).

3bf2a701a5 In the calling convention logic, ValVT is always a legal type,
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

f6e5e02c9b Inside the calling convention logic LocVT is always a simple
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

fef30fcd5e Reapply bottom-up fast-isel, with several fixes for x86-32:
- Check getBytesToPopOnReturn().
 - Eschew ST0 and ST1 for return values.
 - Fix the PIC base register initialization so that it doesn't ever
   fail to end up the top of the entry block.

a DBG_VALUE after a terminator, or emitting any instructions before an EH_LABEL.
