Allow symbols to start from the digit if target requests it. This allows, e.g. pinning
...
variables to specified absolute address. Make use of this feature for MSP430.
This unbreaks PR4776.

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.
