Next round of x87 long double stuff.
Getting close now, basically works.

Add APInt interfaces to APFloat (allows directly2007-09-11T18:32:33ZDale Johannesendalej@apple.com2007-09-11T18:32:33Zurn:sha1:3f6eb7419de437436265831fce92f62498556e08
access to bits). Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling
(untested, probably does not work).

Fold the adjust_trampoline intrinsic into2007-09-11T14:10:23ZDuncan Sandsbaldrick@free.fr2007-09-11T14:10:23Zurn:sha1:f7331b3dd72409e644833ecaf62a0f6db03c97ee
init_trampoline. There is now only one
trampoline intrinsic.

1. Don't call Value::getName(), which is slow.2007-09-10T21:15:22ZChris Lattnersabre@nondot.org2007-09-10T21:15:22Zurn:sha1:87b51bc2b0e9bced27d6fd95573a3f21691a261c
2. Lower calls to fabs and friends to FABS nodes etc unless the function has
internal linkage. Before we wouldn't lower if it had a definition, which
is incorrect. This allows us to compile:
define double @fabs(double %f) {
%tmp2 = tail call double @fabs( double %f )
ret double %tmp2
}
into:
_fabs:
fabs f1, f1
blr
