9b9d35cc05 Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas 
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

65fca605c6 LSR: ignore strides in outer loops. 
Since we're not rewriting IVs in other loops, there's not much reason
to consider their stride when generating formulae.
This should reduce the number of useless formulas considered by LSR.

43cade9bb2 ARM allows '' syntax, not just '#imm' for assembly. 
Backwards compatibility with 'gas'. #imm is the preferered and documented
syntax, but lots of existing code uses the '$' prefix, so we should
support it if we can.

356ad6d232 ARM assembly aliases for BIC<-->AND (immediate). 
When the immediate operand of an AND or BIC instruction isn't representable
in the immediate field of the instruction, but the bitwise negation of the
immediate is, assemble the instruction as the inverse operation instead
with the inverted immediate as the operand.

489e81da30 ARM assembly parsing and encoding for VLD2 with writeback. 
Refactor the instructions into fixed writeback and register-stride
writeback variants to simplify the offset operand (no more optional
register operand using reg0). This is a simpler representation and allows
the assembly parser to more easily handle these instructions.

Add tests for the instruction variants now supported.

previous commit. It is strange that we see it in 32 bits. We already

63cf89d532 The second part of support for generating dwarf for assembly source files. This 
generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each
non-temporary label.

a .s file.  rdar://9275556

4f0b3bb42b Add -unroll-runtime for unrolling loops with run-time trip counts. 
Patch by Brendon Cahoon!

This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.
