New test runtime/ErrorHandling/MachCodeFramesInErrorFile.java added in last merge with main line is failing:

The test fails when parsing the hs_error file, trying to recognize a particular pattern.

The test is using this expression:

        Matcher matcher = Pattern.compile("\\[MachCode\\]\\s*\\[Verified Entry Point\\]\\s* # \\{method\\} \\{[^}]*\\} '([^']+)' '([^']+)' in '([^']+)'", Pattern.DOTALL).matcher(hsErr);

to look for the following kind of sequence in the hs_error file:

[MachCode]
[Verified Entry Point]
  # {method} {0x00007f8694401bf8} 'crashInJava3' '(J)V' in 'MachCodeFramesInErrorFile$Crasher'


With Valhalla, the output in the hs_error file is quite different:

[MachCode]
[Entry Point]
[Inline Entry Point]
[Verified Entry Point]
[Verified Inline Entry Point]
[Verified Inline Entry Point (RO)]
 ;; N1: # out( B1 ) <- in( B5 B4 B8 ) Freq: 1
 ;; B1: # out( B5 B2 ) <- BLOCK HEAD IS JUNK Freq: 1


and doesn't match the expression expected by the test.
