87b665d3de 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.

e3ef744d3e Add CCAssignToStackABISizeAlign for convenience in
dealing with types whose size & alignment are
different on different subtargets.  Use it for x86 f80.

7fef59f7e5 Clarify that fastcc has a problem with nested function
trampolines, rather than with nested functions themselves.

48abc5cf6b 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'.

c85e1716f0 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

6a30811d5c Get X86 long double calling convention to work
(on Darwin, anyway).  Fix some table omissions for
LD arithmetic.

1866f6ec7b 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.

70500805d5 bugfix: fastcall does not require the first two params to be marked 'inreg',
they always get registers.

011bcc8cdd add new CC_X86_32_FastCall calling conv, which describes fastcall on win32.
Factor out a CC_X86_32_Common convention, which is the part shared between
ccc, stdcall and fastcall
