LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound

For PR1064:
...
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.
This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
bits in an integer. The Type classes SubclassData field is used to
store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
64-bit integers. These are replaced with just IntegerType which is not
a primitive any more.
3. Adjust the rest of LLVM to account for this change.
Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types. Future increments
will rectify this situation.

For PR1099:
...
Invert the "isSigned" logic in calls to printType and printPrimitiveType.
We want variables to be declared unsigned by default so that signless
operators like + and - perform the unsigned operation that LLVM expects
by default. Parameters with the sext attribute will be declared signed and
signed instructions will case operand values to signed regardless of the
type of the variable. This passes all tests and fixes PR1099.

Reid Spencer
76d79c7040
For PR1099:
...
Partial fix for this PR. Default function parameters to signed integer, just
like everything else in CBE. The bug was caused by incorrectly introducing
parameter attributes feature by choosing "signed" parameter if the
SExtAttribute was specified. Howeer, if no attribute is specified, this
causes it to become unsigned which is incorrect. Reversing the logic so
that signedness is detected by "not ZExtAttribute" set fixes the issue.
This fixes 197.parser but there is more to do. Any comparison and possibly
other operators involving arguments may need to correctly cast the parameter
before its use, depending on the sign of the operator.

For PR950:
...
Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
type of an function parameter was used to determine whether it should
be sign extended or zero extended before the call. This information is
now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
the parameter attribute information. Although it would have been
convenient to pass in the FunctionType itself, there isn't always one
present in the caller. Consequently, a signedness indication for the
result type and for each parameter was provided for in the interface
to this method. All implementations were changed to make the adjustment
necessary.

Upgrade the ugly darwin 64-bit bswap idiom (bswap %eax / bswap %edx /
...
xchgl %eax, %edx) to llvm.bswap.i64. This compiles:
long long test2(long long A) {
return _OSSwapInt64(A);
}
to:
_test2:
movl 8(%esp), %eax
movl 4(%esp), %edx
bswapl %eax
bswapl %edx
ret
instead of:
_test2:
movl 8(%esp), %edx
movl 4(%esp), %eax
bswap %eax
bswap %edx
xchgl %eax, %edx
ret
GCC manages (with -fomit-frame-pointer) the uglier:
_test2:
subl $4, %esp
movl 8(%esp), %eax
movl 12(%esp), %edx
bswap %eax
bswap %edx
xchgl %eax, %edx
addl $4, %esp
ret

Trivially lower 'bswap $0' into llvm.bswap. This fixes hexxagon with the
...
JIT on darwin/x86, which has htonl implemented as inline asm.
