adc80f98cf LegalizeSetCCOperands() may end up inserting libcalls. They need to be 
properly serialized. Do not clear LastCallSEQ_END until that is done.

0076ca0da9 - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.

de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

f5839a0816 Fix a miscompilation of: 
long long foo(long long X) {
  return (long long)(signed char)(int)X;
}

Instead of:

_foo:
        extsb r2, r4
        srawi r3, r4, 31
        mr r4, r2
        blr

we now produce:

_foo:
        extsb r4, r4
        srawi r3, r4, 31
        blr

This fixes a miscompilation in ConstantFolding.cpp.

875ea0cdbd Expand 64-bit shifts more optimally if we know that the high bit of the 
shift amount is one or zero.  For example, for:

long long foo1(long long X, int C) {
  return X << (C|32);
}

long long foo2(long long X, int C) {
  return X << (C&~32);
}

we get:

_foo1:
        movb $31, %cl
        movl 4(%esp), %edx
        andb 12(%esp), %cl
        shll %cl, %edx
        xorl %eax, %eax
        ret
_foo2:
        movb $223, %cl
        movl 4(%esp), %eax
        movl 8(%esp), %edx
        andb 12(%esp), %cl
        shldl %cl, %eax, %edx
        shll %cl, %eax
        ret

instead of:

_foo1:
        subl $4, %esp
        movl %ebx, (%esp)
        movb $32, %bl
        movl 8(%esp), %eax
        movl 12(%esp), %edx
        movb %bl, %cl
        orb 16(%esp), %cl
        shldl %cl, %eax, %edx
        shll %cl, %eax
        xorl %ecx, %ecx
        testb %bl, %bl
        cmovne %eax, %edx
        cmovne %ecx, %eax
        movl (%esp), %ebx
        addl $4, %esp
        ret
_foo2:
        subl $4, %esp
        movl %ebx, (%esp)
        movb $223, %cl
        movl 8(%esp), %eax
        movl 12(%esp), %edx
        andb 16(%esp), %cl
        shldl %cl, %eax, %edx
        shll %cl, %eax
