15969b664d Check we aren't trying to convert PPC long double. 
This fixes the testsuite failure on ppcf128-4.ll.

5fdce98ebd Do not hold the JIT lock when materializing a function and verify if the 
function has already been codegen'd. This is required by the Java class loading
mechanism which executes Java code when materializing a function.

675fca3ee1 Check that APFloat::convert is not trying to target 
ppc long double, which doesn't work.

This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.

26b54dda58 Implement a bit more softfloat support in 
LegalizeTypes.  Correct the load logic so
that it actually works, and also teach it
to handle floating point extending loads.

98ca33cb59 Fix the handling of va_copy on x86-64. As of llvm-gcc r49920 
llvm-gcc is now lowering va_copy on x86-64, so this completes
the fix for PR2230.

88d2a8459b Provide an explicit list of operands to MakeLibcall, 
rather than having it suck them out of a node.  Add
a bunch of new libcalls, and remove dead softfloat
code (dead, because FloatToInt is used not Expand
in this case).  Note that indexed stores probably
aren't handled properly, likewise for loads.

55efcf86e9 Run SimplifyLibCalls near the beginning, not at 
the end.  It is now run at the same moment as in
llvm-gcc.  Also, run StripDeadPrototypes at the
end, just before running DeadTypeElimination.
This may be useful when doing LTO.  Note that
llvm-gcc runs StripDeadPrototypes but not
DeadTypeElimination.
