42101a805b Rename the CurMultiClass formal parameter of TGParser::AddSubMultiClass 
so that it doesn't shadow the instance variable of the same name.
Make the parameter names in method declarations match the definitions.

dd9b184c19 Change forward declaration of MultiClass to use the "struct" keyword instead 
of "class", so that it matches the subsequent definition.

503cfd4ace Allow a user of libLTO to specify the full pathname of the gcc executable to 
run when assembling.

Wire this up to the gold plugin. You can now pass --plugin-opt gcc=/foo/bar/gcc
and it will run that gcc instead of looking for it on the path.

794fb5b4b3 fix a regression handling indirect results: these need to be considered 
memory operands otherwise the writebacks get lost when the inline asm 
doesn't otherwise have side effects.  This fixes rdar://6839427, though
clang really shouldn't generate these anymore.

40a162f75f Instead of passing in an unsigned value for the optimization level, use an enum, 
which better identifies what the optimization is doing. And is more flexible for
future uses.

06aff30f01 Generalize the cast-of-addrec folding to handle folding of SCEVs like 
(sext i8 {-128,+,1} to i64) to i64 {-128,+,1}, where the iteration
crosses from negative to positive, but is still safe if the trip
count is within range.

e1eefefdc3 Disable the load-shrinking optimization from looking at 
anything larger than 64-bits, avoiding a crash.  This should
really be fixed to use APInts, though type legalization happens
to help us out and we get good code on the attached testcase at
least.

This fixes rdar://6836460

50971fd69c The second part of the change from -fast to -O#. This changes the JIT to accept 
an optimization level instead of a simple boolean telling it to generate code
"fast" or the other type of "fast".

7546bed590 Second attempt: 
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.
