subdirectories to traverse into.
 - Originally I wanted to avoid this and just autoscan, but this has one key
   flaw in that new subdirectories can not automatically trigger a rerun of the
   llvm-build tool. This is particularly a pain when switching back and forth
   between trees where one has added a subdirectory, as the dependencies will
   tend to be wrong. This will also eliminates FIXME implicitly.

These modifiers simply select either the low or high D subregister of a Neon
Q register.  I've also removed the unimplemented 'p' modifier, which turns out
to be a bit different than the comment here suggests and as far as I can tell
was only intended for internal use in Apple's version of gcc.

alignment as well.

Downgrade the alignment of the initial constant island when constant
pool entries are moved elsewhere.

This is all gated by -arm-align-constant-islands.

Also add an MCP member pointing to the machine constant pool.

No functional change intended.

Order constant pool entries by descending alignment in the initial
island to ensure packing and correct alignment.  When the command line
flag is set, also align the basic block containing the constant pool
entries.

This is only a partial implementation of constant island alignment. More
to come.

Remove some remants of the old palign pattern fragment that were still hanging around. Also remove a cast from inside getShuffleVPERM2X128Immediate and getShuffleVPERMILPImmediate since the only caller already had done the cast.

Fixed bug 9905: Failure in code selection for llvm intrinsics sqrt/exp (fix for FSQRT, FSIN, FCOS, FPOWI, FPOW, FLOG, FLOG2, FLOG10, FEXP, FEXP2). Third attempt: simplified checks in test for armv7-apple-darwin11.

Make CR spill and restore use a reserved register. These operations cannot use the register scavenger because the scavenger can only scavenge one register and frame-index elimination may have already grabbed it.

The split point is picked such that the newly created water has the same
alignment as the function. This makes the island suitable for constant
pool entries with potentially higher alignment.

This also fixes an issue where the basic block was split one instruction
too late, causing nonconvergence of the algorithm.

There is still an issue with correctly packing differently aligned
entries in the island.

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.

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.

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.

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.
