684381a73b 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.

bbed9bff31 Make sure to use SwitchSection to switch sections so that we don't accidentally emit 
functions into the .const section.  Whoops.

e1435b7831 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.

bb448515ae 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.

aecebc076b 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.

cf11aefc91 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.

c2c2e353ee 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

6314b5fc35 FORTRAN!!! :( and other similarly unfortunate things mean that on ia64 
one sometimes needs to pass FP args in both FP *and* integer registers.
