7ff0b7a980 Updated pfrexp implementation. 
The original implementation fails for 0, denormals, inf, and NaN.

4cb563a01e Fix ldexp implementations. 
The previous implementations produced garbage values if the exponent did
not fit within the exponent bits.  See #2131 for a complete discussion,
and !375 for other possible implementations.

Here we implement the 4-factor version. See `pldexp_impl` in
`GenericPacketMathFunctions.h` for a full description.

The SSE `pcmp*` methods were moved down since `pcmp_le<Packet4i>`
requires `por`.

Left as a "TODO" is to delegate to a faster version if we know the
exponent does fit within the exponent bits.

Fixes #2131.

1615a27993 Fix altivec packetmath. 
Allows the altivec packetmath tests to pass.  There were a few issues:
- `pstoreu` was missing MSQ on `_BIG_ENDIAN` systems
- `cmp_*` didn't properly handle conversion of bool flags (0x7FC instead
of 0xFFFF)
- `pfrexp` needed to set the `exponent` argument.

Related to !370, #2128

cc: @ChipKerchner @pdrocaldeira

Tested on `_BIG_ENDIAN` running on QEMU with VSX.  Couldn't figure out build
flags to get it to work for little endian.
