62be1a71f4 make this code more aggressive about turning store fpimm into store int imm.
This is not sufficient to fix X86/store-fp-constant.ll

a17f03980f teach scev to analyze X*4|1 like X*4+c. This allows us to produce:

57fc62c8d2 Another step forward in PPC64 JIT support: we now no-longer need stubs
emitted for external globals in PPC64-JIT-PIC mode (which is good because
we didn't handle them before!).

This also fixes a bug handling the picbase delta, which we would get wrong
in some cases.

ae6a305094 * Eliminate calls to CastInst::createInferredCast.
* Add support for promoting unions with fp values in them.  This produces
   our new int<->fp bitcast instructions, implementing
   Transforms/ScalarRepl/union-fp-int.ll

As an example, this allows us to compile this:

union intfloat { int i; float f; };
float invsqrt(const float arg_x) {
    union intfloat x = { .f = arg_x };
    const float xhalf = arg_x * 0.5f;
    x.i = 0x5f3759df - (x.i >> 1);
    return x.f * (1.5f - xhalf * x.f * x.f);
}

into:

_invsqrt:
        movss 4(%esp), %xmm0
        movd %xmm0, %eax
        sarl %eax
        movl $1597463007, %ecx
