4e85e64007 Remove some now-unneeded casts from instruction patterns. With the casts
removed, tblgen produces identical output to with them in.

ab390d045a Do partial inlining in BU. This resolves more call sites. Also add options to merge in globals during recursion and to back annotate DSNodes when function pointers are resolved. This makes PA work for a whole lot more things (unresolved call sites being what has been killing various DSA based passes)

059ca0f5b7 fix some assumptions that pointers can only be 32-bits. With this, we can
now compile:

static unsigned long X;
void test1() {
  X = 0;
}

into:

_test1:
        lis r2, ha16(_X)
        li r3, 0
        stw r3, lo16(_X)(r2)
        blr

Totally amazing :)

7c1fb5f08c Document the subtarget features better, make sure that 64-bit mode, 64-bit
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),

TableGen should emit operand informations for the "required" operands.

instruction may have more operands in addition to the minimum required
operands.

not handling PHI nodes correctly when determining if a value was live-out.

This patch reduces the number of detected live-out variables in the testcase
from 6565 to 485.

the live ranges of these register arguments.

the problem with \n writing CRLF to a bytecode file on windows.

35033efd08 Make the "pruning cloner" smarter. As it propagates constants through the
code (while cloning) it often gets the branch/switch instructions.  Since it
knows that edges of the CFG are dead, it need not clone (or even look) at
the obviously dead blocks.  This should speed up the inliner substantially on
code where there are lots of inlinable calls to functions with constant
arguments.  On C++ code in particular, this kicks in.
