Expand unaligned 32 bit loads from an address which is a constant

offset from a 32 bit aligned base as follows:
ldw low, base[offset >> 2]
ldw high, base[(offset >> 2) + 1]
shr low_shifted, low, (offset & 0x3) * 8
shl high_shifted, high, 32 - (offset & 0x3) * 8
or result, low_shifted, high_shifted
Expand 32 bit loads / stores with 16 bit alignment into two 16 bit
loads / stores.

Split the Add, Sub, and Mul instruction opcodes into separate
...
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:

Fix for PR4235: to build a floating-point value from integer parts,
...
build an integer and cast that to a float. This fixes a crash
caused by trying to split an f32 into two f16's.
This changes the behavior in test/CodeGen/XCore/fneg.ll because that
testcase now triggers a DAGCombine which converts the fneg into an integer
operation. If someone is interested, it's probably possible to tweak
the test to generate an actual fneg.

Add pseudo instructions to the XCore for (load|store|load address) of a
...
frame index. eliminateFrameIndex will replace these instructions with
(LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use.
This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame
pointer elimination. However since they were marked as implicitly using
SP they could not be rematerialised.
