Chris Lattner b7025749e1 When lowering direct calls, lower them to use a targetglobaladress directly 
instead of a globaladdress.  This has no effect on the generated code at all.

Nate Begeman a171f6b20c Patch to clean up function call pseudos and support the BLA instruction, 
which branches to an absolute address.  This is required to support objc
direct dispatch.

Chris Lattner 63985e2892 Make sure to use SwitchSection to switch sections so that we don't accidentally emit 
functions into the .const section.  Whoops.

Chris Lattner fafff9ba1d Make BB and CPI labels use the function number, not the function name as a 
uniquing id.  This makes things happy when the function name is quoted,
preventing labels like LBB"foo"_2.

Chris Lattner 88e234dd49 Add a new option to indicate we want the code generator to emit code quickly, 
not spending tons of time microoptimizing it.  This is useful for an -O0
style of build.

Duraid Madina 4a30d4a460 just some random hacking - calls (particularly indirect) need a lot of 
love (especially with -sched=simple)

Nate Begeman 3ee3e69556 Add the necessary support to the ISel to allow targets to codegen the new 
alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

Duraid Madina 4645db0948 ask for 16-byte aligned jmpbufs. This should unbreak C++ on IA64 (and 
a bunch of other things) but is currently ignored by the code
generator.

Duraid Madina 31071b7471 oops, forgot to load GP for indirect calls, though the old code now commented 
out failed (e.g. methcall) - now the code compiles, though it's not quite
right just yet (tm) ;)

would fix this but it's 3am! :O

Duraid Madina 9b61d3c1e2 FORTRAN!!! :( and other similarly unfortunate things mean that on ia64 
one sometimes needs to pass FP args in both FP *and* integer registers.

Duraid Madina b81b61330e so tablegen was thinking I might want to convert FPs to predicates. 
clever little tablegen!
