ebba07cccf Tablegen generated code already tests the opcode value, so it's not 
necessary to use dyn_cast in these predicates.

ab390189dc Revert r55018 and apply the correct "fix" for the 64-bit sub_and_fetch atomic. 
Just expand it like the other X-bit sub_and_fetches.

was already present, but not hooked up to anything.

15b76de064 Add support for 8 and 16 bit forms of __sync 
builtins on X86.

Change "lock" instructions to be on a separate line.
This is needed to work around a bug in the Darwin
assembler.

e1e9213f95 Make it compile on VC2005: 
- update VC projects.
- Add an overload to llvm::Stream for <<, since std::hex and std::dec have type std::ios_base& (*)(std::ios_base&) in VC++. (templating the function don't work, due to ambiguities)
- add ../ on several include in X86/AsmPrinter/

non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch

718fcee02d Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

74fa421281 Re-enable elimination of unnecessary SUBREG_TO_REG instructions in 
LowerSubregs, and fix an x86-64 isel bug that this exposed.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.

cc784f1662 Re-introduce the 8-bit subreg zext-inreg patterns for x86-32,

efb5d2ce6e Reapply r54147 with a constraint to only use the 8-bit 
subreg form on x86-64, to avoid the problem with x86-32
having GPRs that don't have 8-bit subregs.

Also, change several 16-bit instructions to use 
equivalent 32-bit instructions. These have a smaller
encoding and avoid partial-register updates.

1816900fd1 Add x86 isel patterns to match what would be a ZERO_EXTEND_INREG operation, 
which is represented in codegen as an 'and' operation. This matches them
with movz instructions, instead of leaving them to be matched by and
instructions with an immediate field.
