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.

llvm-svn: 69202

Construct and emit DW_TAG_inlined_subroutine DIEs for inlined subroutine scopes (only in FastISel mode). 

llvm-svn: 69116

Right now, Debugging information to encode scopes (DW_TAG_lexical_block) relies on DBG_LABEL. Unfortunately this intefers with the quality of optimized code. 
This patch updates dwarf writer to encode scoping information in DWARF only in FastISel mode.

Now debug_inlined section is covered by TAI->doesDwarfUsesInlineInfoSection(), which is false by default.

to support C99 inline, GNU extern inline, etc.  Related bugzilla's
include PR3517, PR3100, & PR2933.  Nothing uses this yet, but it
appears to work.

from the assembler:

Error: unknown pseudo-op: `.debug_inlined'

Keep track of inlined functions and their locations. This information is collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) 

Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions. See DwarfWriter.cpp for more information on structure of debug_inlined section.

wanted. Instead, pass back the "const char*". Modify the EmitString() method to
take a "const char*".
