Add and commonize encoder support for all immediates.

Stub out some dummy fixups to make things work.
We can now emit fixups like this:
subl $20, %esp ## encoding: [0x83,0xec,A]
## fixup A - offset: 2, value: 20, kind: fixup_1byte_imm
Emitting $20 as a single-byte fixup to be later resolved
by the assembler is ridiculous of course (vs just emitting
the byte) but this is a failure of the matcher, which
should be producing an imm of 20, not an MCExpr of 20.

The previous fix of widening divides that trap was too fragile as it depends on custom
...
lowering and requires that certain types exist in ValueTypes.h. Modified widening to
check if an op can trap and if so, the widening algorithm will apply only the op on
the defined elements. It is safer to do this in widening because the optimizer can't
guarantee removing unused ops in some cases.

tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
register instruction only works with low registers. Allowing high registers
for the instruction resulted in the assembler choosing the wide (32-bit)
encoding for the mov, but LLVM though the instruction was only 16 bits wide,
so offset calculations for constant pools became incorrect, leading to
out of range constant pool entries.

backend to use X86MCTargetExpr, simplifying a bunch of code.

Fixed the AT&T AsmLexer to report the proper strings
...
for register tokens. Before, if it encountered
'%al,' it would report 'al,' as the token. Now it
correctly reports '%al'.

When CodeGen'ing unoptimized code, there may be unfolded constant expressions

Give DwarfPrinter a protected (but not virtual) destructor. Cppcheck
...
warns about this base class not having a virtual destructor, but since
this class has no virtual methods and neither it or the types derived
from it has a destructor, a protected trivial destructor will do (and
shuts cppcheck up) the trick without the cost of introducing a vtable.

Run codegen dce pass for all targets at all optimization levels. Previously it's
...
only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.

Reintroduce the InlineHint function attribute.
...
This time it's for real! I am going to hook this up in the frontends as well.
The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.
We need some experiments to determine if that is the right thing to do.
