686c4a18f1 Use of vector<bool> causes some horrendous compile time regression (2x)! 
Looks like libstdc++ implementation does not scale very well. Switch back
to using directly managed arrays.

f9ba401bf5 Add special check to avoid isLoop call. Simple, but doesn't seem to speed 
up lcssa much in practice.

880ddb018a Speed up Loop::isLCSSAForm by using a binary search and single-entry cache. 
This reduces LCSSA pass time from 1.5s to 0.96s when run on eon in release+asserts mode.

d41ae8bc0c Replace the SSA update code in LCSSA with a bottom-up approach instead of a top 
down approach, inspired by discussions with Tanya.

This approach is significantly faster, because it does not need dominator
frontiers and it does not insert extraneous unused PHI nodes.  For example, on
252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest
pass in gccas) from 9.14s to 0.74s on my G5.  This code is also slightly smaller
and significantly simpler than the old code.

Amusingly, in a normal Release build (which includes the
"assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA
is in LCSSA form is actually slower than the LCSSA transformation pass
itself on 252.eon.  I will see if Loop::isLCSSAForm can be sped up next.

9ff542f2cc 1. Change use of "Cache" to "Default". 
2. Added argument to instruction scheduler creators so the creators can do
special things.
3. Repaired target hazard code.
4. Misc.

f76d180c95 Fix PR850 and CodeGen/X86/2006-07-31-SingleRegClass.ll. 
The CFE refers to all single-register constraints (like "A") by their 16-bit
name, even though the 8 or 32-bit version of the register may be needed.
The X86 backend should realize what is going on and redecode the name back
to its proper form.

252ad03d7d Change Path::getStatusInfo to return a boolean and error string on an error 
instead of throwing an exception.  This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.
