PIC, and less dense forms of jump tables.

b0636041c8 fix stack corruption! Previously, 16-byte whole-FP-register stores were 
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

get some cute number, and not 0, which is bad.

2b4ea795a2 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

64aa0ea4e9 this is a hack, which may or may not hang around. In short: 
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?
