Propagate changes from my local tree. This patch includes:
...
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.
NOTEs: 1. Documentation will be updated soon.
2. llvm-upgrade should be improved to translate csret => sret.
Before this, there will be some unexpected test fails.

Another step forward in PPC64 JIT support: we now no-longer need stubs
...
emitted for external globals in PPC64-JIT-PIC mode (which is good because
we didn't handle them before!).
This also fixes a bug handling the picbase delta, which we would get wrong
in some cases.

Rewrite the branch selector to be correct in the face of large functions.
...
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model. This fixes assembler errors when compiling 403.gcc with
tail merging enabled.
Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion. Only if branches need expansion are instructions rewritten
and created. This should make branch select faster, and eliminates the
Bxx instructions from the .td file.

lower "X = seteq Y, Z" to '(shr (ctlz (xor Y, Z)), 5)' instead of
...
'(shr (ctlz (sub Y, Z)), 5)'.
The use of xor better exposes the operation to bit-twiddling logic in the

typedef struct {
unsigned prefix : 4;
unsigned code : 4;
unsigned unsigned_p : 4;
} tree_common;
int foo(tree_common *a, tree_common *b) {
return a->code == b->code;
}
Now compiles to:
_foo:
lwz r2, 0(r4)
lwz r3, 0(r3)
xor r2, r3, r2
rlwinm r2, r2, 28, 28, 31
cntlzw r2, r2
srwi r3, r2, 5
blr
instead of:
_foo:
lbz r2, 3(r4)
lbz r3, 3(r3)
srwi r2, r2, 4
srwi r3, r3, 4
subf r2, r2, r3

Go through all kinds of trouble to mark 'blr' as having a predicate operand
...
that takes a register and condition code. Print these pieces of BLR the
right way, even though it is currently set to 'always'.
Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Implement the getRegForInlineAsmConstraint method for PPC. With recent
...
sdisel changes, this eliminates a ton of copies around common inline asms.
For example:
int test2(int Y, int X) {
asm("foo %0, %1" : "=r"(X): "r"(X));
return X;
}
now compiles to:
_test2:
foo r3, r4
blr
instead of:
_test2:
mr r2, r4
foo r2, r2
mr r3, r2
blr
GCC produces:
_test2:
foo r4, r4
mr r3,r4

return X << (C&~32);

...
like:
long long test(long long X, int Y) {
return 1ULL << Y;
}
long long test2(long long X, int Y) {
return -1LL << Y;
}
which we used to compile to:
_test:
li r2, 1
subfic r3, r5, 32
li r4, 0
addi r6, r5, -32
srw r3, r2, r3
slw r4, r4, r5
slw r6, r2, r6

slw r4, r2, r5

_test2:

srw r3, r2, r3
slw r4, r2, r5
slw r2, r2, r6
