x86-32 long doubles are 4-byte aligned on the stack

Eliminate the recently introduced CCAssignToStackABISizeAlign
...
in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values. This seems a neater solution.
It is safe since no legal value type has size 0.

dealing with types whose size & alignment are
different on different subtargets. Use it for x86 f80.

Corrected many typing errors. And removed 'nest' parameter handling
...
for fastcc from X86CallingConv.td. This means that nested functions
are not supported for calling convention 'fastcc'.

Added tail call optimization to the x86 back end. It can be
...
enabled by passing -tailcallopt to llc. The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
elf/pic enabled + callee is in module + callee has
visibility protected or hidden

Vector results may be returned in XMM0 and XMM1, not just XMM0. With

the recent lowering changes, this allows types like <4 x double> to
be returned, using two vector registers.
