Remove ARM isel hacks that fold large immediates into a pair of add, sub, and,
...
and xor. The 32-bit move immediates can be hoisted out of loops by machine
LICM but the isel hacks were preventing them.
Instead, let peephole optimization pass recognize registers that are defined by
immediates and the ARM target hook will fold the immediates in.
Other changes include 1) do not fold and / xor into cmp to isel TST / TEQ
instructions if there are multiple uses. This happens when the 'and' is live
out, machine sink would have sinked the computation and that ends up pessimizing
code. The peephole pass would recognize situations where the 'and' can be
toggled to define CPSR and eliminate the comparison anyway.
2) Move peephole pass to after machine LICM, sink, and CSE to avoid blocking
important optimizations.

This is the first step in adding sane error handling support to LLVMSystem.
...
The system API's will be shifted over to returning an error_code, and returning
other return values as out parameters to the function.
Code that needs to check error conditions will use the errc enum values which
are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are
compatable with the error codes in WinError.h due to some magic in system_error.
An example would be:
if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool.
handle_error(ec);

Reimplement BuildResultOperands to be in terms of the result instruction's

After:

Generalize tblgen's dag parsing logic to handle arbitrary expressions
...
as the operator of the dag. Specifically, this allows parsing things
like (F.x 4) in addition to just (a 4).
Unfortunately, this runs afoul of an idiom being used by llvmc. It
is using dags like (foo [1,2,3]) to represent a list of stuff being
passed into foo. With this change, this is parsed as a [1,2,3]
subscript on foo instead of being the first argument to the dag.
Cope with this in the short term by requiring a "-llvmc-temp-hack"
argument to tblgen to get the old parsing behavior.
