* gc/hipe_darwin_amd64:
Fix hipe memory allocation problems on darwin/amd64
Porting x86 darwin fixes to amd64 darwin hipe asm/m4 code
Automatically enable hipe for darwin/amd64 builds
Allow configure to enable_hipe for darwin/amd64 builds
OTP-8416 HiPE now works in the 64-bit emulator on Mac OS X. (Thanks to
Geoff Cant.)

Compared to GNU as, Mac OS X's assembler uses different directives for
text and global sections, and omits type and size directives
entirely. We also need to mangle symbol names in order to allow
linking with C object files.

* mp/hipe-smp-fixes:
work around hipe_mfa_info_table lock omission
fix hipe loader SMP non-atomicity error
OTP-8397 The loading of native code was not properly atomic in the SMP
emulator, which could cause crashes. Also a per-MFA information
table for the native code has now been protected with a lock
since it turns that it could be accessed concurrently in the SMP
emulator. (Thanks to Mikael Pettersson.)

HiPE maintains per-MFA information such as native code entry
point in a table. This table was thought to be read-only at
runtime, except when the loader populates it, so it employed
no locking. That turned out to be incorrect: if there is an
apply of a previously unseen MFA, a native code stub for that
MFA is created and recorded in the table, causing it to grow.
Work around this for now by slapping a mutex around accesses
to that table.
